Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Which graph represents the function?

f(x) = x(x + 2)

Answer 1

Answer: (B) top right graph

Explanation:

y = x(x + 2) is in intercept form. So, the intercepts are:

• x = 0
• x + 2 = 0 ⇒ x = -2

The only graph that crosses the x-axis at 0 and -2 is the top right graph.
