Vocabulary Related Function: formed by moving all terms to one side & setting them equal to y or f(x). The ROOT or ZERO of an equation is equal to the X-INTERCEPT of the Related Function.
Solve by Graphing: • Move all terms to the RIGHT side of the equation (So… 0 = all terms) • Replace the 0 with y or f(x) • Graph with a table • X-intercept = Solution
