Question

Refer to the graphs in the specified exercises from Section 2.5. For each graph, determine the following: the domain and range (use interval notation), the zeroes of the function (use set notation and write the values in increasing order), the open intervals on which the function is positive or negative (interval notation), the open intervals on which the function is increasing and decreasing (interval notation), and any local max or local min value(s) (write as points separated by commas, if applicable, and write the word none if there is no local max or min). Enter U for ∪ (union), -infinity for −∞, infinity for ∞, and empty for ∅. Hint: For simplicity, write R for R=(−∞,∞). (a) [Exercise 2.5.42.]

the domain and the function, (c) where the function d) interval(s) where the function is or constant, and (e) the location of lue(s). 42. y f(x) (3.5, 0) 5 X -5 44. y h(x)

Domain: Range: Zeroes: Positive: Negative: Increasing: Decreasing: Local max: Local min
