We are given the function to name as f(x) equal to 3x + 12 and we are asked to find the inverse of the function and name it g(x). first step is to extract x, this is equal to (y - 12)/ 3 = x; then exchange the places of x and y, that is (x- 12)/3 = y = g(x). we evaluate f(g(-2)). f(g(x)) is equal to  3*((x- 12)/3) + 12 = x - 12 + 12 = x.   The domain is from negative infinity to positive infinity

Please help the answer are <br> 12<br> 4<br> X<br> X+4<br> -16<br> 16<br> X+12<br> X^2
Lorico [155]
Step 1:
x² + 4x = 192

Step 2:
Take x common:
x ( x + 4) = 192

Length is x and width is x+4

Step 3:

x² + 4x - 192 = 0

Step 4:

x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0

⇒ x=12, x=-16

Because the length can't be -16, the length is 12.
