By | January 2, 2017

Prime Factorization, GCF & LCM In this tutorial students learn how to find the Greatest Common Factor (GCF) and Least Common Multiple (LCM) using Prime Factorization.  Students will also used the TI-84 to verify our results. Sometime GFC is also referred to as GCD, Greatest Common Divisor. Virginia Standards of Learning(SOL) SOL 4.5 The student will… Read More »

## Graphing Quadratic Equations with the TI-84 Plus C

By | December 14, 2016

Graphing Quadratic Equations In this tutorial students will learn about graphing quadratic equations on a TI-84 Plus C graphing calculator.  A quadratic equation is a second degree polynomial.  The largest exponent in a quadratic equation is 2. When graphed a quadratic equation forms a parabola.  A parabola has several distinct parts named the focus, vertex, axis of symmetry and directrix.

## Math Analysis – How to Derive the Inverse Function of a Rational Function – Example 2

By | November 2, 2016

Rational Inverse Function In this tutorial students will learn how to derive the inverse of a rational one-to-one function and then verify those results with the TI-84 Plus C. First, rational functions have numerators and denominators that are both polynomials. Second, an inverse function can only be created if the original function is one-to-one.  One-to-one means that… Read More »
