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

(require htdp/graphing) | package: htdp-lib

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.rkt".

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