Graphs with ______ symmetry are NOT functions
|
x-axis
|
|
|
Explain Origin symmetry
|
when x,y is on the graph and -x, -y is on the graph
|
|
|
Explain the 3 Algebraic Tests for Symmetry
|
1. The graph of an equation has x-axis symmetry if replacing y with (-y) yields an equivalent equation.
2. The graph of an equation has y-axis symmetry if replacing x with (-x) yields an equivalent equation. 3. The graph of an equation has origin symmetry if replacing x with (-x) and y with (-y) yields an equivalent equation |

|
Explain explicit relation
|
If an equation is solved for y in terms of only x and constants, than it is an explicit relation.

|
What is the difference quotient?
|
Gives the slope of the secant line passing through the points (x, f(x)) and (x+h, f(x+h). It is often used to approximate the slope of the tangent line
