Let f(x)=x-4 and g(x)=x²-16 . Perform each function operation and then find the domain. g(x)-f(x)
The domain for g (x) - f (x) = x² - x - 12 will be all real numbers when f (x) = x - 4 and g (x) = x² - 16.
We are given the two functions as:
f (x) = x - 4
g (x) = x² - 16
Now, first, we need to subtract f (x) from g (x).
So, we get that:
g (x) - f (x) = x² - 16 - (x - 4)
g (x) - f (x) = x² - 16 - x + 4
g (x) - f (x) = x² - x - 12
Now, the domain of the function will be all real numbers as it will be defined for all the real numbers.
Therefore, we get that the domain for g (x) - f (x) = x² - x - 12 will be all real numbers when f (x) = x - 4 and g (x) = x² - 16.

Which multiple choice response is true?
O Decreasing on (-*, 0); increasing on (0, *)
O Increasing on (-x, ∞)
O , Increasing on (-*, 0); decreasing on (0, *)
O Decreasing on (-∞, ∞)
True response is that the function represented by the graph is Increasing on (-∞, 0) and decreasing on (0, ∞)
A function is said to be increasing in its domains if the value of its range is increasing in that domain.
Similarly, if the function is decreasing in its domain then it's range must be decreasing with the domain.
When the value of x(domain) is increasing on the left side. The value of y(range) is increasing constantly. But when the value of x increases further after 0, then the value of y is decreasing constantly.
So we can say, the following function represented on the graph is increasing in the interval of ( -∞,0) and decreasing in (0,∞).
As per the situation described in the graph the option third which say increasing on (×,0) and decreasing on (0,×).

[tex]\frac{ln(e^2)}{2}[/tex] = 1, by properties of logarithm.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Given: [tex]\frac{ln(e^2)}{2}[/tex]
Now,
By property of logarithm, [tex]log_b(a)^m=m(log_b(a))[/tex],=> [tex]\frac{ln(e^2)}{2}[/tex] = [tex]\frac{2 (ln(e))}{2}[/tex]
=> [tex]\frac{ln(e^2)}{2}[/tex] = ln (e)
AS we know that ln (e) = 1 (by properties of logarithm),=> [tex]\frac{ln(e^2)}{2}[/tex] = 1
Hence, [tex]\frac{ln(e^2)}{2}[/tex] = 1, by properties of logarithm.

For which values of A, B, and C will Ax + By = C be a horizontal line through the point (−4, 2)?
The values of A, B, and C will Ax + By = C be a horizontal line through the point (−4, 2) are ( 0, B, 2B)
In the above question, a horizontal line is given whose equation is Ax + By = C which passes through a point (-4, 2)
We can make two observations from the given information of horizontal line passes through point (-4,2) which are as follows:
1. The slope of a horizontal line will be parallel to the x-axis whose slope will be, m=0.
2. The given point and the line meet at (-4,2).
Now as the point (-4,2) lie on the line it will satisfy the equation of the horizontal line
We get,
A(-4) + B(2) = C
-4A + 2B = C ..... eqn 1
Also, we can write the given equation in the slope-intercept form which is
y = mx + c
By = -Ax + C
y = [tex]\frac{-A}{C}[/tex]x + [tex]\frac{C}{B}[/tex]
So, we can imply that m = [tex]\frac{-A}{C}[/tex] = 0
A = 0
Putting this in eqn 1 we get,
-4A + 2B = C
0 + 2B = C
C = 2B
Hence, we conclude that values of A, B, and C will Ax + By = C be a horizontal line through the point (−4, 2) are ( 0, B, 2B)

The inverse of f₁(x)=b^(x-h) is not equal to a vertical stretch or compression of g: TRUE
What accurately do we mean by Logarithmic Functions?The logarithmic function is the inverse of the exponential function.A logarithm to the base b is the power to which b must be increased in order to obtain a specific number.For example, log28 is the power to which 2 must be raised to generate eight. Clearly, 23 = 8, so log28=3.So,
Given inverse function: f₁(x)=b^(x-h)
First, find out the inverse of this function.
So, let f₁(x) = yThen, y=b^(x-h)Switch the variables x & y as follows;
x=b^(y-h)Solve for y as shown below and take logarithm both sides:
log(x) = (y-h)log(b)y=h+ log(x)/log(b)So,
f₁^(-1)(x)= h+log(x)/log(b)f₁^(-1)(x)= h+logb(x)f₁^(-1) (x)= g(x)+hFrom the first equation we get the inverse of as f₁ follows:
f₁^(-1) (x)= g(x)+hTherefore, the statement "the inverse of f₁(x)=b^(x-h) is not equal to a vertical stretch or compression of g" is TRUE.
