1 The graph of a function is a picture of all of its (input,output) pairs. We put the inputs along the horizontal axis (the $\,x\,$-axis), and the outputs along the vertical axis (the $\,y\,$-axis).  Thus, the graph of a function $\,f\,$ is a picture of all points of the form [beautiful math coming...
