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.

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

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
