Question

Given f(x) = -3x + 5, find f(-6).

Answer 1

Answer:

23

Step-by-step explanation:

Since it says f(x) that means that when we see f(-6) we are substituting x for -6.

This means that the equation will become

f(-6) = -3(-6) + 5

First multiply -3 and -6 (18)

f(-6) = 18 + 5

Next add 18 and 5 (23)

This means that f(-6) = 23

Answer 2

23

This problem is basically asking you to plug in -6 for x and solve using the order of operations (PEMDAS)

$f( - 6) = - 3( - 6) + 5$

$f( - 6) = 18 + 5$

$f( - 6) = 23$
