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? (1 point)


(1, 0), (4, 0), (7, 0)
(−1, 0), (−4, 0), (−7, 0)
(1, 0), (4, 0), (−7, 0)
(−1, 0), (−4, 0), (7, 0)

Answer 1

set each factor equal to zero and solve for x
you can do it in your head
