ENGL 1005T Study Guide - Quiz Guide: The Intercept, Trigonometric Functions, Junkers J.I
Document Summary
Question 1 page 196: the x-intercepts are 1, 1, and 2. The y-intercept is 2: the x-intercepts are approximately 2. 88 and 3. 63. Question 2 page 196: since the function is even degree and has a positive leading coefficient, the graph extends from quadrant 2 to 1. , y : since the function is odd degree and has a positive leading coefficient, the graph extends from quadrant 3 to 1. Question 3 page 196 a: average rate, average rate: The average of the two rates of change approximates the instantaneous rate at x = 2. The degree is 4: from the table and information given in part a): 48 = 24a a = - 2 y = - 2(x - 1)2 (x + 3)2: answers may vary. Also, since the function has even degree, a negative leading coefficient means the graph extends from quadrant 3 to quadrant 4 and has at least one maximum point.
