An object is launched from a platform. its height (in meters) , x seconds after the launch, is modeled by h(x) = -5(x+1)(x-9) what is the height of the object at the time of launch?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above
