Question

If f(x)=5x^2 and g(x)=x-2 what is (fog)(-3)

Answer 1

(fog)(-3) = 125

Explanation:

So, we need to first evaluate g(-3) and then plug the value of g(-3) into f(x) to find (fog)(-3). So, let's do that:

`g(-3) = -3-2 = -5`

`f(g(-3)) = f(-5) = 5(-5)^2 = 5(25) = 125`

Thus, (fog)(-3) = 125.
