Given the (entire) graph of the function {{MATH_1}}, answer the following questions. {{CMD_2}} {{ENV_3}} {{CMD_4}} {{CMD_5}} Find the domain of {{MATH_6}}. {{MATH_7}} Find the range of {{MATH_8}}. {{MATH_9}} {{CMD_10}} Find a formula for {{MATH_11}}. {{CMD_12}} On the interval {{MATH_13}}, the graph of the function {{MATH_14}} is a line. Therefore, on that interval, {{MATH_15}}, for some constants {{MATH_16}} and {{MATH_17}}. Similarly for {{MATH_18}} on the interval {{MATH_19}}. {{CMD_20}} {{MATH_21}} {{CMD_22}} {{CMD_23}} Let {{MATH_24}} and {{MATH_25}}.
