QUESTION 24 Section 2.5 #38a For Exercises 37 through 40, determine (a) interval(s) where the function is increasing, decreasing or constant Graph each function using shifts of a parent function and a

Section 2.6 #10

By carefully inspecting each graph given, (a) identify the function family; (b) describe or identify the end behavior, vertex, axis of symmetry, and x- and y-intercepts; and (c) determine the domain and range. Assume required features have integer values. 10. q(x) = x2+ 2x + 8

Section 2.4 #10

Determine whether the mappings shown represent functions or nonfunctions. If a nonfunction, explain how the definition of a function is violated. 10.

Section 2.6 #92

Graph each function using shifts of a parent function and a few characteristic points. Clearly state and indicate the transformations used and identify the location of all vertices, initial points, and/or inflection points.

Students do not need to submit a graph.

Section 2.7 #22

Graph each piecewise-defined function and state its domain and range. Use transformations of the toolbox functions where possible.
