Using the function f(x) = -5x + 2 find f(-3)

substitute the -3 in the equation.

f(x)=-3

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

f(x)= +15 +2

f(x)= 17

f(-3) = 17

Step-by-step explanation:

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

we want to find f(-3)

to do so, we simply substitute -3 for x

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

multiply -5 and -3

f(-3) = 15 + 2

add 15 and 2

f(-3) = 17

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
