a. Draw the graphs of f(x) = x^2 - 4x and g(x) = 1/f(x) on the same grid.

b. Explain how the graph of f(x) = x^2 - 4x can be used to obtain the graph of y= g(x).

I have done part (a); it's part (b) that has me confused. All I know for sure is that the graph of f(x) has two zeroes, at x = 0 and x = 4. But I am unsure how to use this (or the rest of the graph) to answer the question.

Thank you for your help! :wink:
