The function can be graphed to demonstrate this further. On the graph where f(x)=0, the curve is just the x-axis, which always has the same y-value of 0.
How to find the domain of a function ?Domaine:The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Given the function f(x)=0,
since this is a constant function (that is, for any value of x, f(x)=0, the limit of the function as x→a, where a is any real number, is equal to 0.
More specifically, as a constant function,f(x) maintains the same value for any x. f(1)=f(2)=f(π)=f(e)=f(−(1258567)/(44))=0. Further, as a constant function, f(x) is by definition continuous throughout its domain. Note, however, that if one arrives at a constant function via division or multiplication of non-constant functions (for example, (8x)/(x), there will still exist a discontinuity where the original denominator was0).
Graphing the function will further prove this point. On the graph f(x)=0, the curve is simply the x-axis, which maintains a constant y-value of 0 no matter the x-value.

331 students went on a field trip. Six
buses were filled and 7 students
traveled in cars. How many students
were in each bus?
The number of students in each bus are 54 students .
Given that, 331 students went on a field trip. Six buses were filled and 7 students traveled in cars.
Now you may get that only 7 students out of 331 are travelled in cars whereas others travelled by bus.
number of total students travelled by bus are 331-7 = 324 students
Therefore 324 students travelled in 6 buses.
Number of students travelled in each bus = 324/6 = 54 students.
Therefore number of students travelled in each bus is 54 students .
verification:
number of buses = 6
number of students in each bus = 54
Therefore total number of students in 6 buses = 6*54 = 324 students.

If two functions share the same domain and codomain and have values that are consistent across all domain elements, they are said to be equivalent.
Consider the function,
[tex]f(x)=5(\frac{1}{5})^{x}[/tex]
Now,
Positive x-values and negative x-values are switched by a reflection over the y-axis, which also swaps the values of x and x.
So,
[tex]f(-x)=f(x)[/tex]
The reflection of the function f(x) across the y axis will be:
[tex]f(x)=5(\frac{1}{5})^{-x}[/tex]
Therefore, the equivalent function will be:

[tex]f(x)=5 \times ((\frac{1}{5})^{-1})^{x} \\f(x)=5(5)^{x}[/tex]

A chemist needs to mix a 2% acid solution and a 10% acid solution to make 600 mL of a 5% acid solution. write and solve a system of equations to find the volume of the 2% solution and the volume of the 10% solution that the chemist will need.
Points points points!!
By solving a system of equations, we can see that the chemist needs to use 375 mL of the 2% acid, and the other 225% of the 10% acid.
How to write and solve the system of equations?
Let's define the variables that we will need to write our system of equations:
x = mL of the 2% acid solution used.y = mL of the 10% acid solution used.We know that the chemist wants to make 600mL of a 5% acid solution, so we can write the system of equations:
x + y = 600
x*0.02 + y*0.10 = 600*0.05
If we isolate y on the first equation, then we get:
y = 600 - x
Now we can replace that on the other equation so we get:
x*0.02 + (600 - x)*0.10 = 30
With this, we can get the value of x.
x*0.02 + 60 - x*0.10 = 30
-x*0.08 = 30 - 60 = -30
x = 30/0.08 = 375
So the chemist needs to use 375 mL of the 2% acid, and the other 225% of the 10% acid.

mary robertson sells tires at a large car service center she earns 10 commission on the first $1000 15 on the next $2000 and 20 on sales of more than $3000 last
Her total commission was $560.
As 10% of the first $1,000, 15% of the next $2,000, and 20% of sales beyond $3,000 are commissions that she receives. She sold $3,400 worth of tires last week.
What does "total commission" mean?
The commission serves as a benefit or an inducement for the worker to close agreements so that the business can increase revenue and profits. The total commission is calculated by multiplying the total sales by the commission percentage.
After dividing the outcome by 100, multiply the sale price by the commission percentage. Perform the subsequent calculation: Each blue gadget costs $70. The salesman receives a 14% commission on each sale, or $9.80.
The percentage or fixed payment connected to a specific number of sales is referred to as a "commission rate." A commission, for instance, can be $30 or 6% of sales.
It is therefore $560.

Considering that the amounts in USD are rounded to the nearest hundredth, the use the following rule
1 euro - 1.35 USD.
It asks if the Ruiz family will be getting the most accurate answer.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we suppose a 1000 euros amount, them:
