Question 1186177: Given the function, f(x)=4 - 5x,do the following:
1. Find its inverse
2. Sketch the graph of the function by assigning
values from the domain of the function.
3. Prove that they are inverses of each other.

You can now substitute 4-5x for x in the inverse formula and simplify, and see what happens.
You can also try to substitute (4-x)/5 for x IN THE ORIGINAL FORMULA for f(x), simplify and see what happens.
You can do the graphs of the lines.
Put these on the same coordinate system:
