Piecewise Linear Function
Maximum output values the highest possible outputs in a function
Minimum output values the lowest possible inputs in a function
Non-linear function a function that doesn't make a straight line on a graph
x-intercept where y = 0. This is also called the function zeroes
y-intercept the y-value where the graph crosses the y-axis. ALL y-intercepts happen when x = 0
zeroes of a function
increasing function
decreasing function
Turning points also means verticies

inputs
outputs
average rate of change how fast the output is changing compared to the input
