Above is part of the graph of a function . It's impossible to show the entire graph in a finite region because it is too large. The left side of the graph is the left side of a parabola; use your imagination to imagine the rest of the parabola extending off to the left. The right side of the graph is part of a line; if you can see its right endpoint then you can see the entire right side of the graph; if you can't see its right endpoint then the line extends infinitely far to the right.
Given this information, find the following. In parts (a)-(e) write your answers using interval notation:
(a) Domain: (b) Range:
In parts (c)-(e) do not include endpoints in the intervals. (People disagree on whether or not to call a function "strictly increasing" at an endpoint). In other words, pretend all your intervals are open. (c) Set on which is strictly increasing: (d) Set on which is strictly decreasing: (e) Set on which is constant:
In parts (f),(g) list the -coordinates () of the local maxima and minima. Use commas to separate distinct values if there are more than one. Enter NONE if there are none.
(f) Local maxima: (g) Local minima:
