Question
**Exponential Function Range Exercise**

**Task:** Find the range of the exponential function. Write the range using interval notation.

**Graph Explanation:**

The graph shows an exponential function. The curve starts very close to the x-axis on the left and rises sharply as it moves to the right. The graph is positioned in the first quadrant, indicating that the y-values are positive as x increases.

- **Axes:** 
  - The horizontal axis is labeled "x," with increments from -10 to 10.
  - The vertical axis is labeled "y," with increments from -10 to 10.

- **Curve Behavior:**
  - The curve approaches the x-axis as x becomes more negative, but never touches or crosses it, indicating the graph approaches zero but does not go below it.
  - The curve increases rapidly as x becomes more positive, moving upwards beyond y = 10.

**Conclusion:**

The exponential function shown on the graph has no maximum limit for y and never reaches or goes below y = 0. Therefore, the range of the function is all positive real numbers, expressed in interval notation as: \( (0, \infty) \).
