Exercise 9 Page 327

Start by making a table of values.

Vertical shrink by a factor of 2 and vertical shift 3 units upward

Practice makes perfect

We want to start by drawing a graph of the given exponential function. f(x)= 2^x Because the base of the function is greater than 1, we know that this is an exponential growth function. Let's make a table of values.

x 2^x y=2^x
- 2 2^(- 2) 0.25
- 1 2^(- 1) 0.5
0 2^0 1
1 2^1 2
2 2^2 4

The ordered pairs ( - 2, 0.25), ( - 1, 0.5), ( 0, 1), ( 1, 2), and ( 2, 4) all lie on the function. Now we will plot and connect these points with a smooth curve.

Comparison to the Shown Graph

We are asked to compare the shown graph to the graph of f(x). Let's draw them together!

Notice that the graph of f(x) should be vertically shrink by a factor of 2 and vertically shifted 3 units upward to get the given graph.
