Find the Domain and Range - log base 3 of x+2

$- \log_{3} (x) + 2$

Set the argument in $\log_{3} (x)$ greater than $0$ to find where the expression is defined.

$x > 0$

The domain is all values of $x$ that make the expression defined.

Interval Notation:

$(0, \infty)$

Set-Builder Notation:

${x | x > 0}$

The range is the set of all valid $y$ values. Use the graph to find the range.

Interval Notation:

$(- \infty, \infty)$

Set-Builder Notation:

${y | y \in ℝ}$

Determine the domain and range.

Domain: $(0, \infty), {x | x > 0}$

Range: $(- \infty, \infty), {y | y \in ℝ}$
