Let f(x) = 2x + 2. solve f−1(x) when x = 4. a. 1 b.3 c. 4 d.10

A is correct

Step-by-step explanation:

Given function: f(x)=2x+2

First we will find the inverse of f(x)

f(x)=2x+2

Set f(x)=y,           y=2x+2

Switch x and y , x=2y+2

Solve for y to get inverse of f(x)

[yex]y=\dfrac{x-2}{2}[/tex]

Thus,

Now, we find the value of inverse function at x=4

Put x=4 into inverse function.

Hence, The value of inverse function at x=4 is 1

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
