y = e^{x}

$y = e^{x}$

Step 1

The range is the set of all valid

y

$y$ values. Use the graph to find the range.

Interval Notation:

(0, \infty)

$(0, \infty)$

Set-Builder Notation:

{y | y > 0}

${y | y > 0}$

Step 2

⎡ ⎢ ⎣ \begin{matrix} x^{2} & \frac{1}{2} \sqrt{π} & \int x d x \end{matrix} ⎤ ⎥ ⎦

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
