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!!!

Steffi -

Here's the easy way. In column A (starting in A2) type a series of
typical X values from within the range of interest. In B2 type the
formula, referring to A2 as the variable X, and fill this down alongside
all of your X values. I can't parse your formula, but here's an example.

Suppose you want Y = 12 + 13 X - 0.003* X^2

In B2 enter this formula:

=12+13*A2-0.003*A2^2

You can fill this down by selecting B2, and double clicking on the small
black square at the bottom right of the highlighting rectangle.

Now make your chart from the data in columns A and B. Make an XY chart,
not a line chart.

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.
