Which point is an x-intercept of the quadratic function
f(x) = (x – 8)(x + 9)?
(0,8)
(0,–8)
(9,0)
(–9,0)

(-9,0)

Step-by-step explanation:

Well if you graph this equation amd track down all the points the only point that the parabola will go through is (-9,0).

Choice D is correct.

Step-by-step explanation:

We have given a quadratic function.

f(x) = (x – 8)(x + 9)

We have to find x-intercept of the quadratic equation.

x-intercept is a point where the value of y is zero on the graph.

Putting y  = f(x)  = 0 in given equation, we have

0 = (x-8)(x+9)

Applying Zero-Product Property to above equation, we have

x-8  = 0 or x+9  = 0

x  = 8 or x = -9

Hence, x-intercepts of given quadratic function are (8,0) and (-9,0).

From choices, Choice D is correct.
