Your Answer is D 
And to make your math life easier you may want to consider getting a graphing calculator. Personally I think it's easier typing it in a graphing calculator rather than solving it out on paper. But you don't have too, it's just a friendly suggestion :)

For these questions, as multiple choice, it can sometimes be faster just to check the answers in the equations and see which one provides true statements every time.
