AP CALCULUS 1001 TI-89 pt.3
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]
Four Requirements: Graph using an appropriate window. (End Behavior, Roots, Max/Min) Evaluate. Find roots ( zeros, x-intercepts) Find intersections
Zeros • Graph • [F5] Math • #2: Zero
Intersection • Graph • [F5] Math • #5:Intersection
Draw Inverse: Graphing by finding the Inverse. Draw Inverse Function: [<>][F3] [F6] #2: DrawInv [F6] #1: ClrDraw
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? ---------------------------------------------------------------
EXAMPLE (cont): Graph Find an appropriate Window. Find the Intersection. Answer. TRY:nSolve(y1(x)=y2(x),x)
