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.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
