  1. Finding zeroes and y intercepts via the Calculator Zeroes - using the Trace function yintercepts - Using the Calculate function Algebraically Tomorrow Asymptotes

  2. Zeroes and y Intercepts DEFINITIONS: • Zeroes are points, where a function crosses the x axis  specifically, f(x) = 0 • y intercepts are points, where a function crosses the y axis  specifically, x = 0

  3. Finding zeroes by Tracing on Calculator • < Y= > • enter f(x) • < GRAPH > • if necessary, resize window • < 2nd > < CALC > • 2 < ENTER > (for zero) • move cursor to left of zero (left bound) • < ENTER > • move cursor to right of zero (right bound) • < ENTER > Guess ? • < ENTER >

  4. Finding y intercepts via the Calculate feature on Calculator • < Y= > • enter f(x) • < GRAPH> optional to view the function graphically • if necessary, resize window to view • < 2nd > < CALC > • “1” (for value) • “0” (entering a value of zero for X) • < ENTER >

  5. Zeroes and X Intercepts When sketching functions, the first algebraic step is to identify the zeroes and the y intercepts. • Zeroes are points, where a function crosses the x axis  specifically, set f(x) = 0 and solve for x. • y intercepts are points, where a function crosses the y axis  specifically, set x = 0 and solve f(x)

  6. Examples & Practice 1st Solve Algebraically, then check your answers using your calculator: This is Homework

  7. Asymptotes When sketching functions, the next step is to identify the asymptotes, if any. ……Wednesday ? …… (depends on Plan/Explore Testing Schedule)
