For a school assignment I have to turn a number of equations into a graph.
for example y=-56 over 2197 (X+38.5)to the third -7 when X = -45.

HELP!!!

In addition to Jon's do-it-yourself approach, also look at
PLOT manager

Does something similar but concentrates its efforts where the function
is more curvy.
