Answer:
Option C. y= ( -x)^2 -4
Step-by-step explanation:
If we have a function
and we want to transform it into a function g(x) that is equal to f(x) displaced c units down on the y-axis, then we must do:

In this case we want to move the function 4 units down, then:

Finally, to reflect the function on the y-axis. must do 
Then we have the following function:

The answer is option C
Answer:
x=13
Step-by-step explanation:
3(x-2)-3=30
3x-6-3=30
3x-9=30
3x=30+9
3x=39
x=39/3
x=13
X² - 6x +9
x -3
x -3
D) (x - 3) (x -3) is your answer
To check, do your FOIL
x(x) = x^2
x(-3) = -3x
-3(x) = -3x
-3(-3) = 9
x^2 -6x +9 True
hope this helps
