2. IV. Graphing Preliminaries –1. Define a function [<>] [F1] y = –2. Viewing Window [<>] [F2] Window –3. Graph Menus [<>] [F3] GRAPH F2 Zoom F6 Style F4 –4. Alternate Paths [F4] [APPS]

3. Four Requirements: Graph using an appropriate window. (End Behavior, Roots, Max/Min) Evaluate. Find roots ( zeros, x-intercepts) Find intersections

4. Zeros Graph [F5] Math #2: Zero

5. Graph [F5] Math #5:Intersection Intersection

6. Draw Inverse: Graphing by finding the Inverse. Draw Inverse Function: [<>][F3] [F6] #2: DrawInv [F6] #1: ClrDraw

7. EXAMPLE: Job A pays $40,000 and promises a 4% annual raise. Job B pays $30,000 and promises a 6% annual raise. When will the two jobs pay the same? When will Job B pay more? ---------------------------------------------------------------

8. EXAMPLE (cont): Graph Find an appropriate Window. Find the Intersection. Answer. TRY: nSolve(y1(x)=y2(x),x)
