value of the independent variable.
Function - Answer-A relation in which exactly one element of the range is paired with
each element of the domain.
Intercept - Answer-The point at which a line or curve cuts across another line, curve, or
surface.
Line Symmetry - Answer-Figures that match exactly when folded in half have line
symmetry.
End Behavior - Answer-Describes the values of a function at the positive and negative
extremes in its domain.
y-intercept - Answer-The y-coordinate of the point where the line crosses the y-axis
x-intercept - Answer-The x-coordinate of the point where the line crosses the x-axis
