Answer:
f^-1(x) = ( x + -1 )³
Step-by-step explanation:
f(x) = ∛x + 1
y = ∛x + 1
we have to make x the subject to find the inverse
y - 1 = ∛x
( y - 1 )³ = x
so Inverse: f^-1(x) = ( x + -1 )³
4 times 312 = 1,248 = 312 times 4 = 1,248
Hope this helps, sorry if it didn't.
Slope = -1
If y value decreases...and then x increases...then 1/-1 which is = to -1.
