2.  Input variable goes on the horizontal (x)
axis.
 Output variable goes on vertical (y) axis.
 Example:
 This graphs shows
the function f(x).

3.  Move left/right to the given input
value.
 From there, move up/down to find the
output value.
 Find:
 f(-2)
 f(0)
 f(2)

4.  Evaluate each expression using the
graph.
 g(0)
 g(2)
 g(-4)
 g(3)

5.  Evaluate:
 h(-4)
 h(1)
 h(-2.5)
 h(3)
 h(0)

6. f (x)  2x 3
 Use the functions above to evaluate
these expressions:
 f(2)
 g(4)
 h(1)
g(t)  7  2t
