uTo graph using rectangular coordinates (Y =)

You can graph functions that can be expressed in the format y = f(x).

Example To graph y = 2x

+ 3x – 4

Use the following View Window parameters.

Xmin = –5 Ymin = –10

Xmax = 5 Ymax = 10

Xscl = 2 Yscl = 5

1. In the set-up screen, specify the appropriate graph type for F-Type.

!Z1(Y =)Q

2. Input the rectangular coordinate (Y =) expression.
