Question

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.

Answer 1

Well, i know that a non linear function always has a number power greater than 1, and a linear function only has a number power 1 or less.

Hope this helps

Answer 2

The correct options are B and D.

Explanation:

Consider the provided function

`y=-16x^2+48x+64`

The provided function is a quadratic function.

A polynomial function with highest exponent equal to 1 is known as linear functions. Nonlinear functions are all other functions.

The provided function has the exponent 2 which is greater than 1.

Thus, the provided function is a nonlinear function.

Also, the rate of change of a quadratic function does not remain the same.

Therefore, the correct options are B and D.
