You can compare y-values for more than one equation for a given set of x-values. Enter equations into the editor for Y1, Y2, and so on, for as many equations as you have. Then set TblStart and ΔTbl values in the
Table Setup menu and press to view the table of values. Use the and keys to navigate across the equations and the and
keys to scroll through values of x in the table.
Lab Practice
Use a table to find y for the equation for the given values of x. Indicate the TblStart and ΔTbl values you use.
a. y = 2x - 2 for x = 2, 5, 8, and 11 b. y=4xforx=1,8,15,and22
Stephanie is growing two varieties of flowers for a show taking place in three months. The height y in inches of Flower A after x months can be modeled by the equation y = 2x + 1. Flower B grows according to the equation y = 3x - 2. Stephanie will plant the flowers at the same time and monitor their height at the end of each month. If Flower A and Flower B are the same height, she will use them to make an arrangement to present at the flower show.
c. How would Stephanie simulate the growth of each flower?
d. What would Stephanie enter into the calculator to simultaneously
model the growth of Flower A and Flower B?
e. What TblStart value should Stephanie use?
f. What ΔTbl value should she use?
g. How tall are Flower A and Flower B at the end of each month?
h. Will Stephanie be able to create an arrangement of Flowers A and B for the flower show? Explain.
