Compute: {{MATH_198}} {{CMD_199}} This may seem difficult at first. Perhaps the first thing to do is look at a graph of {{MATH_200}}: {{CMD_201}} {{ENV_202}} {{CMD_203}} Now we can graph {{MATH_204}}: {{CMD_205}} {{ENV_206}} {{CMD_207}} Recall, {{MATH_208}} is in fact a piece-wise defined function {{MATH_209}}
