The gravity on the moon differs from that on Earth. The function f(x)=-2x^2+30x+32 models an objects height, in feet, from the moon’s surface x seconds after being launched.

Question

If x>0, which statement is true?

Answer 1

If x>0, it means that the object has been launched and some time has passed since then. Therefore, the statement "the object is in motion above the moon's surface" is true.
