Question

Identify the discontinuities, graph, and find the zeros of the rational function
f(x) = (4x^2-36x)/(x-9)

Answer 1

definitely at x=9 you have a discontinuity (removable)

Answer 2

heh, thanks.

Answer 3

sorry, forgot zeros. do you need them?

Answer 4

Can I have, like, the whole equation? My teacher didn't explain anything and I get absolutely nothing.

Answer 5

now that the function is factored, do you see where the zeros will occur? and what the graph will look like?
