What is the value of f(-3) if f(x)=5(2-x)

The answer is 25.

Step-by-step explanation:

What you have to do here is just replace "x" in the equation with -3. In other words, you plug in -3 to f(x).

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

To negatives makes a positive.

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

f(-3) = 5(5).

5 times 5 is 25.

f(-3) = 25.

So your answer is 25.

the value of f(-3) is 25

Step-by-step explanation:  f(-3)                     f(x)=5(2-x)

If x=-3 and you subtract negative 3 from 2 you get a positive 5 and when you multiply across the parenthesies you get 25 so f(-3)=25
