Assume f(x)=-2x+8 and g(x)=5x. what is the value of (fog)(3)? a.3x+8b.-22c.29d.17

Option B. -22

Step-by-step explanation:

The given function are f(x) = -2x + 8 and g(x) = 5x

We have to calculate the value of (fog)(3).

Since (fog)(x) = f [g(x)]

f [g(x)] = -2(5x) + 8

         = -10x + 8

Now ( fog ) (3) = f [g(3)] = (-10) × 3 + 8

                      = -30 + 8

                    = -22

Therefore, Option B. -22 is the answer.
