Answer:
The graph of g(x) is the graph of f(x) stretched by 3 and shifted 8 units up
Step-by-step explanation:
Given


Required
Compare g(x) and f(x)
We have:

Rewrite as:
![g(x) =3[x^2] + 8](https://tex.z-dn.net/?f=g%28x%29%20%20%3D3%5Bx%5E2%5D%20%2B%208)
Substitute:

This means that:
<u>3f(x)</u>
f(x) is stretched vertically by a factor of 3
<u>+8</u>
Then shifted upwards by 8 units to give g(x)
For this case the generic equation of the line is given by:

Where,
m: slope of the line
b: intersection with the y axis
For this case we have:

Therefore, substituting values in the generic equation we have:

Answer:
The equation of the line is:

option 1
Answer:
The answer to your question is: letter B
Step-by-step explanation:
A) No, it is not a function because it has two open circles.
B) Yes, it is a function because it passes the vertical line test.
C) Yes, it is a function because it passes the horizontal line test.
D) No, it is not a function because it does not pass the horizontal line test.
