→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

Answer:
4.5
Step-by-step explanation:
The value of x that makes f(x) = -3 is ...
4/3x -9 = -3
4/3x = 6 . . . . . . add 9
x = 6(3/4) = 18/4 = 9/2 = 4.5 . . . . multiply by 3/4
f^-1(-3) = 4.5
