Hello,

you have to examine a piecewise defined function:

I'm going to show you how to type this function into your calculator:

1. Open the editor. Go to y1= and press F3

2. Pick from the catalog the commandwhen(

3. The complete input line looks like this:

y1= when(x ≤ 6, when(x ≤ 2, 4x,8),-1/2*x+11)

You get the sign ≤ by typing <=. Your calculator transform these two signs into one sign.

4. Open the editor. Use the following settings:

xmin = -2

xmax = 10

xscl = 1

ymin = -2

ymax = 10

yscl = 1

xres = 3

I've attached 2 screenshots:
