Roots With Calc3
- 1. Do Now: Determine the nature of the roots, find the roots, y-int, turning point, max or min, sketch graph: y = x 2 + 3x - 4 Aim: How do we find the roots and vertex using the graphing calculator? (3rd and Final Try) MB43 3/12/09 Lomas HW: For each list the: a) Nature of Roots b) Roots c) y-intercept d) Axis of Symmetry e) Turning Piont f) Concave up or down g) Sketch the graph 1) y = x 2 - 8x - 6 2) f(x) = x 2 + 4x - 3
