Can anyone help with this question?

Answer 1

If you alter the "c" value, then you are moving the graph up (or down if c is negative).

Since you are shifting the graph up, the y-intercept ("h" in your graph) will move up.

Since you are shifting the graph up, then the maximum will shift up.

Since you are shifting the graph up, then the x-intercept ("t" in your graph) will increase (move to the right).
