Question

Find all intercepts and asymptotes:
x^2-4x
And can someone tell me how to find them in general?

Answer 1

your intercetps will be when y equals zero. i assume the function is y=x^2-4x?

Answer 2

therefore factor out an x and get x(x-4)=0 one x =0 and another is x-4=0 --> x=4

Answer 3

so your intercepts are x=0 and x=4 your asymptotes will be there if there are places in the function is undefined. therefore with this particular problem there are not any asymptotes.
