How can you test for X-axis symmetry
A function has x-symmetry if, by substituting all y’s for negative y’s, the function reduces back into its original form.
How can you test for symmetry with respect to the origin?
A function has origin symmetry if, by substituting all y’s for negative y’s, and all x’s for
negative x’s, the function reduces back into its original form.
What is the point slope form of a line? Identify all parts of the point slope formula.
The Point-Slope form of a line is y - y1 = m(x - x1) where m is the slope of the line and (x1, y1 ) is a point on the line.
