Question 600402: apply the quadratic formula to find the roots of the given function, and then graph the function.
0 = x2 - 9
How do I graph this with no y
0 = x2 � 9
Move x to the right side of the equation
X^2-9=0
Add 9 to both sides
X^2=9
Take the square root of both sides to eliminate the exponent
X=+-(sqr)/9
3 is a perfect square
X=+-3
Substitute + for +-
X=3
Substitute - for +-
X=-3
