Question 17 PLEASE HELP given the function: f(x) =3x+7. Find the value of y when x=-8

Answer 1

→Answer:

y = -17

→Step-by-step explanation:

Well first off the f(x) in the equation f(x) = 3x + 7 can also be written as y,

y = 3x + 7

So if x is -8 we need to plug it in for x and solve, simple as that :)

y = 3(-8) + 7

y = -24 +7

y = -17
