For the equation y^2=x+9, list the intercepts, and check for symmetry.
Find the square root of both sides
y = +sqrt%28x+%2B+9%29
y = -sqrt%28x+%2B+9%29
y = 0 when x = -9, the x intercept
Find the y intercept, x = 0
y = +sqrt%280+%2B+9%29
y = +3
and
y = +\-sqrt%28x+%2B+9%29
y = -3
:
looks like this
+graph%28+300%2C+200%2C+-20%2C+10%2C+-10%2C+10%2C+sqrt%28x%2B9%29%2C+-sqrt%28x%2B9%29%29+
Axis of symmetry is the x axis
