Question

What is the inverse of the logarithmic function f(x)=log2x?

Answer 1

Explanation:

What is the inverse of the logarithmic function

f(x) = log2x?

(b) or f –1(x) = 2x

the second question

The point (–1, 0.5) lies on the graph of

f –1(x) = 2x. Based on this information, which point lies on the graph of f(x) = log2x?

(B) or (0.5, –1)

Answer 2

Answer: Choice B)
`f^(-1)(x) = 2^x`

Exponentials undo logarithms, and vice versa. The base of the log and the exponential are the same in this problem.
