Step-by-step explanation:

Step 1: Define

f(x) = 5(2 - x)

f(-3) is x = -3

Step 2: Evaluate

1. Substitute:                    f(-3) = 5(2 - -3)
2. Simplify:                        f(-3) = 5(2 + 3)
3. Add:                              f(-3) = 5(5)
4. Multiply:                        f(-3) = 25

Answer 2

Answer:

25

Step-by-step explanation:

Plug in -3 for x.

f(x)= 5(2-x)

f(-3)=5(2-(-3))

f(-3)=5(5)

f(-3)=25
