Answer:

(3,0), (4,0), (5,0)

on the x-axis at 3, 4 and 5

Step-by-step explanation:

This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")

0=(x-5)(x^2-7x+12)

0=(x-5)(x-3)(x-4)

0=x-5, 0=x-3 & 0=x-4

x=5, x=3, x=4

This is where the graph crosses the x-axis.
