Peter Drucker suggests that operational objectives should be SMART, which means:

State the inputs and outputs of the following relation. Is it a function? {$\left(-3,5\right),\left(0,2\right),\left(3,5\right)$}

State the inputs and outputs of the following relation. Is it a function? {$\left(2,5\right),\left(0,2\right),\left(2,9\right)$}

Find the domain and range of the following graph (write your answer using interval notation).
