#### 1.13`` Graphing Functions: "graphing.ss"

( require htdp/graphing )

The teachpack provides two functions for graphing functions in the regular (upper right) quadrant of the Cartesian plane (between 0 and 10 in both directions):

> > procedure

> > ( graph-fun f color) → true

> f : ( -> number? number? )
> color : symbol?

Draws the graph of f with the given color.

> > procedure

> > ( graph-line line color) → true

> line : ( -> number? number? )
> color : symbol?

Draws line, a function representing a straight line, with a given color.

For color symbols, see Simple Drawing: "draw.ss".

In addition, the teachpack re-exports the entire functionality of the drawing library; see Simple Drawing: "draw.ss" for documentation.
