What is meant by function operation?Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, multiplication, and division.
Let the two functions be f and g then f(x) = 7x + 5 and g(x) = x².
we have to calculate (f + g)(x)
Which is equivalent to:
(f + g)(x) = f(x) + g(x)
Taking the two functions and substituting them into this expression, we get,
f(x) + g(x) = (7x + 5) + (x²)
simplifying the above function, we get
f(x) + g(x) = x² + 7x + 5
Therefore, (f + g)(x) = x² + 7x + 5.
We must also determine the domain of the new function. However, because this is a second-order function with no denominators, logarithms, or roots, there are no restrictions on the value of x; thus, the domain is all real numbers.

The value of K is 2 so that the point A lies on the line given by the equation A (2,1), 3x+ky=8.
Given: Equation is 3x+ky=8
Points A (2,1)
We need to determine the value for K
3x+ky=8 — 1 (Take as equation 1)
Substitute the points in equation 1
So, we take x = 2 and y = 1
3(2) +k (1) = 8
6+k = 8
k = 8 - 6
k = 2
When graphing points on a coordinate plane, it is often helpful to find the value of k that makes the point lie on a line. For this problem, k = 2 so that A (2,1), 3x+ky=8.

Let f(x)=2 x²+8 and g(x)=x-3 . What are f+g and f-g ? What are their domains?
Domain of f + g ( x) = R and f - g ( x) = R
Given :
F(x) = 2x^2 + 8 and g(x) = x-3
From this, we get to know that f(x) and g(x) assume real values for all values of x.
Hence, domain (f)= Real(R) and domain (g)= real ( R ) .
Therefore D (f) and D(g) are Real Number
Now,
A > (f + g ) : R ----> R is given by (f + g) (x)
= f(x) + g(x) = 2x^2 + 8 + x- 3
= 2x^2 + x + 5
Hence, domain ( f + g ) = Real ( R )
B > (f – g) : R---> R is given by ( f-g ) (x)
= f(x) – g(x) = 2x^2 + 8 – ( x – 3)
= 2x^2 -x + 11
Hence, domain ( f - g ) = Real ( R ) .

Write each expression in simplest form. (x⁴/x⁻¹)⁻¹/₅
The simplest form of the expression [tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex] is [tex]\frac{1}{x}[/tex].
The simplest form of a fraction is one with a reasonably prime denominator and numerator. It indicates that, except for 1, there is no common factor between the fraction's numerator (upper portion or top) and denominator (lower part or bottom).
A fraction is a number that has been expressed as a quotient by dividing the numerator by the denominator. Both are integers in a simple fraction. In a complex fraction, a fraction can be found in either the numerator or the denominator.
An expression is made up of a number, a variable, or a combination of a number, a variable, and operation symbols. Two expressions joined by an equal sign form an equation.
Consider the expression,
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex]
Now we know,
[tex]x^{-1}=\frac{1}{x}[/tex]
Therefore,
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{\frac{x^4}{x^{-1}} })^{\frac{1}{5} }[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{x^{-1}}{x^4})^{\frac{1}{5}[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{x \times x^4})^{\frac{1}{5}[/tex]
Using the exponential rule,
[tex]n^{b} \times n^{a} = n^{a+b}[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = (\frac{1}{x^{5}} )^{\frac{1}{5}[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = \frac{1}{x^{5 \times \frac{1}{5} }}[/tex]

For each annual rate of change, find the corresponding growth or decay factor.+ 500%
The corresponding growth factor of +500% is 6
The formula for the annual rate of change is
1 ± r (1)
where r = rate of change
and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.
According to the question we have been given the growth that is +500%. Since there is plus sign therefore it is a growth factor.
Thus, r = + 5
Putting this value in equation (1) we get
