Graphs of Functions

	Definition

	Representation of a function with a straight line or curve on a Cartesian plane.

8.2.1 Constructing a table of values

A table of values can be constucted to determine the corresponding value of ordered pair \((x,y)\) before the graph is drawn.

Steps to draw a graph:

(i)		Construct a table if values for the given function

(ii)		Draw and label each axis with the given scale or any suitable scale.

(iii)		Plot the point \((x,y)\) for the ordered pairds from the table.

(iv)		Join the points to form a straight line or a smooth curve.
