Which function represents the inverse of function f?

Here you are multiplying by 3 then adding 5. When doing the inverse, you would do the opposite.

Start with x. then subtract by 5. Itvwould be x-5.

Then divide by 3. So it would be (x-5)/3 which is 1/3x-5/3 which is D

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
