What are the x-intercepts, rounded to the nearest tenth if necessary, of the function y = one-tenthx2 - 15? Check all that apply.

-12.2 and 12.2

Step-by-step explanation:

Since the function is a parabola, there will be two x-intercepts. If you put the function into a graphing calculator, the two x-intercepts are - 12.247 and 12.247. If you round them both to the nearest tenth, you will get - 12.2 and 12.2.
