CPM Homework Help : CALC Problem 1-113

Create a piecewise defined function that will generate the graph below. .

Step 1:

Notice that there are two pieces that meet at x = 5. So the boundary will be x = 5.

Step 2:

Examine the first piece. What parent graph does it resemble? What transformation has been made? Write its equation.

Step 3:

Examine the second piece. What parent graph does it resemble? What transformation has been made? Write its equation.

Step 4:

Since the y-intercept and the point $(9,6)$ are given on the graph, you can check your work for steps 2 and 3. Here's how: Substitute $(0,6)$ to the first piece (does it work?) Substitute $(9,6)$ to the second piece (does it work?)

Step 5:

Assemble the piecewise function. Remember that the boundary is $x = 5$ .
