Answer 1

K

Explanation:

Let's look at the equation.

`h=-at^(2)+bt+c`

This is a standard negative polynomial equation.

So changing the c value will basically move the graph up/down.

`I` is true because if it moved up or down, the h-intercept would change.

`II` is true because if it moved up or down, the maximum would change.

`III` is true because if it moved up or down, the t-intercept would be moved left or right.
