If f(x)=2x+1/x-4, what is the value of f^-1(3)? a. 22/7 b. 19/11 c. 8/3 d. 13 e. 11

D

Step-by-step explanation:

To find inverse function, we need to follow the steps:

1. Change f(x) to y

2. Interchange x and y

3. solve for new y

4. Change y to

Let's do this with the function given:

To find , we plug in 3 into the inverse equation:

D is the correct answer.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
