Reading domain and range off a graph
A graph shows the domain and the range without any formula. How far left and right the graph goes is the domain (the inputs). How far down and up it goes is the range (the outputs). Read the edges.
Reading a graph. Domain: read left to right along the bottom, from where the graph starts to where it ends. Range: read bottom to top along the side, from its lowest point to its highest. A connected graph gives an inequality. Separate points give a list.
