Answer
Domain: $\mathbb{R}$
Range: $[0,\infty)$
Work Step by Step
Domain: set of inputs = set of all real numbers.
(the arrows extend to both sides)
Range: set of outputs = interval $y\geq 0$
(the x-axis is the line $y=0$, and the values on the right rise without bound)
Domain: $\mathbb{R}$
Range: $[0,\infty)$
