Notes
... Zeros can be found by factoring and setting the equation equal to zero. Ex) f(x) = 5x2 + 10x 5x(x – 2) = 0 Factor by GCF 5x = 0 and x – 2 = 0 Set each term = 0 x = 0 and x = 2 Solve for x 5x and (x – 2) are the factors. x = 0 and x = 2 are the zeros. Ex) g(x) = x2 – 10x + 9 (x – 9)(x – 1) Factor x ...

Creating a Table of Values with the Graphing Calculator
... Some tables do not require the use of a calculator, since we work with small numbers. Nevertheless, knowing how to work with the graphing calculator will make it easier to make tables for more complicated equations. How can we create a table of values with the graphing calculator? Let us generate th ...
