1 Approximating Zeroes Learning Objective: to be able to find all critical points of a polynomial function. Warm-up (IN) Describe the graph: 1. 2.

2 Notes! Ex 1: Find the y-int, zeroes and turning points of the following functions using the calculator! The key is to find a window that includes ALL zeroes on your calculator Y-int - -6 zeroes - -2.18, 1.57 Local max - (-.48, -4.75) Local min - (-1.51, -7.5) (.87, -10.26)

3 Y-int - zeroes - -.87,.27 Local max - (1.37, 3.60) Local min - (-.37, -1.6), 2.1

4 HW – Finding zeroes wksht Out – sketch the graph of, accurately labeling all critical points Summary – Today I learned… Don’t forget about POW!!
