Answer: B
Step-by-step explanation:
To solve this problem, we first need to find the inverse of f(x). Then, you would plug in x=8. To find teh inverse, you switch y with x and x with y, then solve for y.
y=2x+5 [switch y with x and x with y]
x=2y+5 [subtract both sides by 5]
x-5=2y [divide both sides by 2]
y=(x-5)/2
Now that we have the inverse function, we plug in x=8 and solve.
y=(8-5)/2 [subtract]
y=3/2
Now, we know that f⁻¹(8)=3/2.

Answer:
8x^9
Step-by-step explanation:
(2x^3)^3 =
First, to raise a product to an exponent, raise eve3ry factor to the exponent.
Second, to raise a power to a power, multiply powers.
= 2^3 * (x^3)^3
= 8 * x^9
= 8x^9
