The tables below show two functions. For each set of data:
slamgirl [31]
The first table, representing <em>f</em>(<em>x</em>), is linear.  The data have a constant rate of change or slope:
<em />(between the first two points):  <em>m</em> = (<em>y</em>₂ - <em /><em>y</em>₁)/(<em>x</em>₂ - <em>x</em>₁) = (22-18)/(-1--2) = 4/(-1+2) = 4/1 = 4.  The rate of change  between any two points is the same:
(between the last two points):<em>  m</em> = (34-30)/(2-1) = 4/1 = 4.

The second table, representing <em>g</em>(<em>x</em>), is exponential.  The data points are multiplied by the same constant between successive points.  2*2 = 4; 4*2= 8; 8*2 = 16, etc.
