Me asap emma throws an object upward from a hill that is 64 feet high. the object has an initial velocity of 48 feet per second. the function y = -16x2 + 48x + 64 represents the height of the object, y, in terms of the time elapsed after the object is thrown, x. what statements about this function are true? a. the function is a linear function. b. the function is a nonlinear function. c. the function has a constant rate of change. d. the function does not have a constant rate of change. e. the function is a decreasing function.

oh b this is a hard question

Step-by-step explanation:

i will answer it gimme a few mins to learn this things

Options B and D are correct.

Step-by-step explanation:

The given equation is :

We can see that it is a quadratic equation.

Hence it is non linear.

The rate is dependent on x, so it does not have a constant rate of change  also.

We can check this :

At x= 0, y = 64

At x=1, y =

Hence, the function does not have a constant rate of change.

So, the answer is :
