Enter values of independent variable into c1 


Enter values of dependent variable into c2 

2. Find the Regression Equation 
Press F5 key 


Press right arrow key 


Choose appropriate regression 

NOTE: In this case I chose ExpReg (i.e., Exponential Regression) 

Press down arrow key once, then type c1 into box for x, then ENTER 

NOTE: You may need to press ALPHA key to turn on/off letters.

Press ENTER (to exit) 

3. Graph the Regression Equation with the Data 
Press 2^{nd}, then ESC (to quit editor) 


Press DIAMOND key, then F1 (for Y=)
