Write a function that repersents this process:
A:Take a number,x.
B: Multiply it by4.
C: Subtract 2 from the result
Then find the inverse of this function. Does the inverse represent the reverse of the process above ? Explain why or why not.

The function:
Start with x and multiply it by 4
4x
then subtract 2
y=4x-2

To find the inverse, switch x and y and solve for y.
x=4y-2
Add 2 to both sides
x+2=4y
Divide by 4 on both sides
(1/4)x+1/2=y

I don't quite understand what it means by "Does the inverse function represent the reverse of the process" but hopefully the inverse can get you started!
