Based on the uploaded problem:

• Graph Type: Exponential function.
• Horizontal Asymptote: A dashed line is shown, which indicates the graph approaches but does not touch this line.

Step 1: Domain

The domain of an exponential function is all real numbers, because you can input any $x$-value into the exponential function, and it will yield a corresponding $y$-value.

• Domain: $x \in (-\infty, \infty)$ or "All reals."

Step 2: Range

The graph of an exponential function typically approaches a horizontal asymptote but never crosses it. Based on the graph:

• The horizontal asymptote is at $y = 0$, meaning the function never reaches or dips below $y = 0$.

• The $y$-values are strictly greater than 0 ($y > 0$).

• Range: $y > 0$.

Final Answer:

(a) Range: $y > 0$
(b) Domain: $x \in (-\infty, \infty)$

Here are 5 related questions for further exploration:

1. How would the graph change if the asymptote moved to $y = -2$?
2. What is the range and domain of a logarithmic function?
3. How do transformations (shifts, stretches, reflections) affect the domain and range of an exponential function?
4. How do we identify the asymptote of an exponential function algebraically?
5. Can an exponential function have a range that includes negative values?

Tip: Always verify the asymptote and direction of the graph before determining range.
