Question

F(x)= -2x + 2; Find f(5)

Answer 1

If f(x) = -2x + 2, f(5) can be found by substituting in the value 5 for x in the equation:

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

Our first step in simplifying this expression is to perform the multiplication as outlined by the order of operations (PEMDAS).

f(5) = -10 + 2

Finally, we must get our final answer by adding together the remaining terms.

f(5) = -8

Hope this helps!
