Reading functions from graphs

Reading functions from graphs

Standard function graphs showing direct proportion, a parabola, a modulus graph, a reciprocal graph and an inverse-square graph

A function assigns exactly one output to each permitted input. The graph of y=f(x)y=f(x)y=f(x) contains every point (x,f(x))(x,f(x))(x,f(x)), so a point (p,q)(p,q)(p,q) lies on the graph precisely when q=f(p)q=f(p)q=f(p).
