To call Atlanta from Boston, the long distance charges C are $0.37 for the first minute and $0.33 for each additional minute t (or portion thereof). Draw a graph of C versus t. Is this an example of continuous or discontinuous function? Explain.

C= 0.37 + 0.33(t-1)

when t= 0 C= 0.04

when C=0 t= 0.1212

just plot (0, 0.04) and (0.1212, 0) in x,y graph.

x, y. x, y
