Question

If k and r are constants, the graph of y = (x - r)^3(x - k)^2 does which of the following?A. 'Bounces off' the x-axis at r and kB. Passes through the x-axis at k and rC. 'Bounces off' the x-axis at k, and passes through the x-axis at r.D. Passes through the x-axis at k, and 'bounces off' the x-axis at r.

Answer 1

we have that

y = (x - r)^3(x - k)^2

the function Passes through the x-axis at k and r

answer is option B
