To find an inverse function first replace f(x) with y
f(x) = 8*sqrt(x)
y = 8*sqrt(x)
Then, simply switch the places of the x and y.
x = 8sqrt(y)
Now solve for the new y by squaring both sides (to get rid of the root)
x^2 = 64y
divide to get
y = x^2/64. This is the inverse function or option C.

Answer:
Step-by-step explanation:
It's a 30-60-90 triangle. The sides of a 30-60-90 triangle are in the ratio 1:√3:2
The side opposite the 90° angle is 12√3, so the side opposite the 30° is (12√3)/2 = 6√3.
The side opposite the 60° angle is (6√3)√3 = 18
x = 18
y = 6√3
