Question 359922: Find the intercepts and use them to graph the equation y=x^2-9
Answer by nyc_function(2741) (Show Source): You can put this solution on YOUR website!
Let y = 0

0 = x^2 - 9

0 = (x - 3) (x + 3)

x - 3 = 0

x = 3

x + 3 = 0

x = -3

===================

Let x = 0

y = (0)^2 - 9

y = -9

The intercepts are: x = -3, x = 3, y = -9
