Answer:
Option D is correct.
Step-by-step explanation:
f(x)= 9x^2 -12
Let y = 9x^2 - 12
Switch places of x and y and solve for y
x = 9y^2 - 12
Adding 12 on both sides
x + 12 = 9y^2
Dividing both sides by 9
x+12/9 = y^2
=> Taking square root on both sides
=> 
Replace y with g(x)

Option D is correct.
The answer to this is (6,-2)
Answer:
y = 7x
y = 2x -3
y = 3
x = -2
Step-by-step explanation:
- <em>Slope-intercept form: y= mx+b</em>
- <em>Parallel lines have same slope</em>
a)Parallel to y=7x+2 through the point (0,0)
<u>
This line will have a form:</u>
<u>Considering the given point of (0,0), to find the value of b:</u>
<u>The line is: </u>
b)Slope of 2 through the point (0,−3)
<u>
Solving as above:</u>
- y= 2x + b
- -3 = 2*0 + b ⇒ b = -3
- y = 2x -3
c)A horizontal line through the point (0,3)
<u>
A horizontal line will have constant value for y for any value of x:</u>
d)A vertical line through the point (−2,0)
<u>A vertical line will have constant value of x for any value of y:</u>
