- This lesson explains the basic functions of the calculator: Using Calculator on Demand.

Specific topics within this lesson include:

- Graphing simple functions (linear, quadratic, rational, and absolute value)
- Zooming on a graph
**Plotting different types of functions**- Linear function example:
*f(x) = Ö*5*x* - Quadratic function example:
*f(x) =*3200 + 80*x*- 4*x*^{2} - Quadratic function example:
*f(x) =*7*x*-*x*^{2}( p/8 +1/2 ) - Cubic function example:
*f(x) =*264*x*- 68*x*^{2}+ 4*x*^{3}

- Linear function example:
- Changing the graphing window to user-defined values
- Finding the intersection of two graphs
- Finding the minimum of a function
- Finding the maximum of a function
- Finding the
*x*-crossings (real roots) of a function - Fitting linear functions to data
- Fitting exponential functions to data
**Solving Systems of equations in two variables**
