You have to understand the problem clearly before trying to answer the question. Only thing that needs to be done to answer the question is adding 5 with f(x). This will yield the required result.
g(x) = f(x) + 5
= (4x^2 - 8) + 5
= 4x^2 - 8 + 5
= 4x^2 - 3
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.

Answer:
(0, 1)
Step-by-step explanation:
y - 4x = 1 crosses the y-axis at (0, 1)
Answer:
The equation of the second line is;
y = 4x - 27
Step-by-step explanation:
Firstly, we need the slope of the first line
To get the slope, we need the equation in the general form of ;
y = mx + c
where m is the slope of the line
Thus, we have in this case, to divide through by -5
That will give the slope value as -5/20 = -1/4
If two lines are perpendicular, the product of their slopes is -1
The slope of the line we want to calculate, let us call it m
m * -1/4 = -1
-m = -4
m = 4
So we want to write the equation of a line with slope 4 and point (8,5)
We proceed to use the point-slope form
That will be;
y-y1 = m(x-x1)
y-5 = 4(x-8)
y-5 = 4x-32
y = 4x -32 + 5
y = 4x -27
