Question

A polynomial function can be written as (x − 1)(x − 4)(x + 7). What are the x-intercepts of the graph of this function

Answer 1

x=1, x=4, x= -7

^These would be your answers.

Answer 2

In order to find x-intercepts, you need to solve each binomial when it is equal to zero.

(x - 1)(x - 4)(x + 7)

x - 1 = 0
x = 1

x - 4 = 0
x = 4

x + 7 = 0
x = -7
