What is the inverse of the logarithmic function f(x) = log2x? f –1(x) = x2 f –1(x) = 2x f –1(x) = logx2 f –1(x) = 1/log2x

B is the correct option.

Step-by-step explanation:

We have to find the inverse of the logarithmic function

Below are the steps to find the inverse:-

Step 1:-

Set f(x) =y

Step 2:-

Interchange x and y

Step 3:-

Solve for y

We know the relation:-

If

Using this relation, we have

b=2

Step 3:-

The value of y is the inverse of the function.

B is the correct option.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
