# What is the domain and range of d(s)= 0.006s^2?

Aug 30, 2015

Domain: $s \in \mathbb{R}$
Range: AAd>=0; d in RR
$d \left(s\right) = 0.006 {s}^{2}$ is valid for all values of $s \in \mathbb{R}$
For $\forall s \in \mathbb{R} , {s}^{2} \ge 0 \Rightarrow {0.006}^{2} \ge 0$
furthermore, as $\left\mid s \right\mid \rightarrow + \infty , d \left(s\right) \rightarrow + \infty$
therefore the range of $d \left(s\right)$ is $\left[0 , + \infty\right)$
