Question

The correct answer to this is A, right?
A polynomial function can be written as (x - 1)(x - 4)(x + 7). What are the x-intercepts of the graph of this function?

a. (1, 0), (4, 0), (7, 0)
b. (-1, 0), (-4, 0), (-7, 0)
c. (1, 0), (4, 0), (-7, 0)
d. (-1, 0), (-4, 0), (7, 0)

Answer 1

(x - 1)(x - 4)(x + 7) = 0

x - 1 = 0 or x - 4 = 0 or x + 7 = 0

x = ??? or x = ??? or x = ???

Answer 2

I'm using the zero product property for step 2

Answer 3

So it would be C then?

Answer 4

correct
