1 Cos(x^2) (x−3)(x3) Zooming and Recentering To zoom, use the zoom slider To the left zooms in, to the right zooms out When you let go of the slider it goes back to the middle so you can zoom more You can clickanddrag to move the graph around Euler's number (2718Directrix y = 5 4 y = 5 4 Select a few x x values, and plug them into the equation to find the corresponding y y values The x x values should be selected around the vertex Tap for more steps Replace the variable x x with 0 0 in the expression f ( 0) = − ( 0) 2 2 ( 0) f ( 0) = ( 0) 2 2 ( 0) Simplify the result Y 2x 2-2x+5
