Question

1. Write an equation for the function g represented in the graph

2. Explain how to determine if the point (25, -613) is on the graph of function g.
3. Justify whether the point (25,-613) is on graph of function g.

Answer 1

1) y = -x² + 12

2) plug in x = 25 and y = -613 in the equation. If it's a true statement, then (25, -613) is on the function g

3) y = -x² + 12

-613= -25² + 12

-613 = -625 + 12

-613 = -613

A true statement
