Find the x-intercepts.
-$$f ( x ) = x ^ { 2 } + 10 x$$
A) No x-intercept
B) $x$-intercepts $( 0 , - 10 )$ and $( - 10,0 )$
C) x-intercepts $( 0,0 )$ and $( 10,0 )$
D) $x$-intercepts $( 0,0 )$ and $( - 10,0 )$

Quizplus · Accepted Answer

To find the x-intercepts, we set y = 0 and solve for x. Thus, we get:
$$x^2 + 10x = 0$$
$$x(x + 10) = 0$$
So the x-intercepts are (0,0) and (-10,0). Therefore, the answer is choice D.
