Question

omain, range, and evaluate exponential function
my ixl learning assess
algebra 2 > z.1 domain and range of exponential functions efd

what is the range of this exponential function?
$y = 9^x$
${y \mid y > 0}$
all real numbers
${y \mid y > 9}$
${y \mid y = 9}$
${y \mid y = 0}$

domain and range of exponential functions: equations

Explanation:

Step1: Analyze exponential function form

For $y = a^x$ where $a>0,a
eq1$, $a^x$ is always positive.

Step2: Apply to given function

Here $a=9>0$, so $9^x > 0$ for all real $x$.

Step3: Define the range

The set of all possible $y$-values is $\{y \mid y > 0\}$.

Answer:

$\{y \mid y > 0\}$
