Astudent claims that the inverse of f(x)=4x−8f(x)=4x−8 is f−1(x)=14x+k. f−1(x)=14x+k. for the case where the student's claim is true, what must be the value of k?

k=2

Step-by-step explanation:

We are given that f(x)=4x-8[/tex] and inverse of the given function

We have to find the value of k.

We have f(x)=4x-8

Let y=4x-8

Then , 4x=y+8

Then ,

Comparing with given inverse function then we get '

k=2

Hence, the value of k must be 2.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
