Do I really need a graphing calculator?

Beginning with first-year algebra, it’s appropriate to start using a graphing calculator, even though it is rarely required. Concepts such as basic function graphing, polynomials, quadratics, and inequalities are better visualized when students can both write out the equations and use an electronic input.

Why are graphing calculators so expensive?

Due to the high market price caused by high demand, he guesses that the company can boast a profit margin of over 50 percent. As Mic reports, Texas Instruments maintains their monopoly with services like 1-800-TI-CARES and workshops that teach teachers how to use the devices.

How do you calculate on a graph?

Use the y=mx+b formula.

1. In the formula, you will be solving for (x,y).
2. The variable m= slope. The slope is also noted as rise over run, or the number of points you travel up and over.
3. In the formula, b= y-intercept. This is the place on your graph where the line will cross over the y-axis.

Why is TI 84 so expensive?
