Exercise 2 Page 322

Make a table to find ordered pairs. Then, plot and connect the points with a smooth curve.

Graph:

Domain: All real numbers
Range: y>0

Practice makes perfect

To graph the given exponential function, we will first make a table of values.

x	3^(x+2)	f(x)=3^(x+2)
- 4	3^(- 4+2)	≈ 0.11
- 2	3^(- 2+2)	1
0	3^(0+2)	9
1	3^(1+2)	27

Let's now plot and connect the points ( - 4, 0.11), ( - 2, 1), ( 0, 9), and ( 1, 27) with a smooth curve.

We can see in the graph that the range is all real numbers greater than zero. The domain of exponential functions is all real numbers. Domain:& All real numbers Range:& y>0
