CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS

3: Minimum

Minimum

will find the minimum

y

-value between your identified

lower bound

and

upper

bound

and it will visually move the cursor to this

(

x, y

)

coordinate.

Example:

Find the minimum

y

-value between the

x

-values of 0 and 2.

Press

to use the

Minimum

command. For the lower bound, use the arrow keys to

move the cursor near an

x

-value of 0 and then press

. Notice that there is now a triangle

towards the top of the screen marking your lower bound. For the upper bound, use the arrow

keys to move the cursor to the right, near an

x

-value of 2. When you press

, the calculator

will find an estimate of the minimum

y

-value.
