Question

for the function p(x)=x(x-7)(x+5) find the y-intercepts and the x-intercepts (enter the x-intercepts increasing order, separting by commas or none)

Answer 1

p(x) is already factored. set each factor equal to 0 and sove for x. those are your x intercepts.

Answer 2

So, when you set x=0, you get the y-intercept, and if the outcome of p(0)=0, then the y-intercept is also a x-intercept. To find the rest of the x-intercepts, simply get x-alone in each ().

Answer 3

for the y intercept, plug in x = 0 and solve for y.
