What are the zeros of the function?

What are points on the graph that represent zeros of the function?
f(x) = (x² + 2x − 8) (x − 6)

---

Zeros of a function are the x-intercepts (where the graph hits the x-axis.  Also, where the value of y is equal to zero.  

f(x) represents the y-value, so set it equal to zero and solve for x.

f(x) = (x² + 2x - 8)(x - 6)
(x² + 2x - 8)(x - 6) = 0   {set f(x), the y-value, equal to zero}
(x + 4)(x - 2)(x - 6) = 0   {factored the trinomial into two binomials}
x + 4 = 0   or   x - 2 = 0   or   x - 6 = 0   {set each factor equal to zero}
x = -4  or  x = 2  or  x = 6  {solved each equation for x}

zeros of the function would be the x-intercepts of -4, 2, and 6
The points on the graph would be (-4,0) , (2,0), and (6,0)
