graph a function where every single input corresponds to the same output

Question

dddgraph a function where every single input corresponds to the same output

Answer 1

The input is traditionally shown as x in a function and the output as y. If they are identical then y=x, which is a straight line graph with slope 1 passing through the origin (0,0). To draw it pick a value of x and y (5, for example) and let the line pass through (0,0) and (5,5).
