Question

Transcribed Image Text:The image displays a graph of the exponential function, specifically the natural exponential function \( y = e^x \). The graph is plotted on the Cartesian coordinate plane with the horizontal x-axis ranging from -4 to 6 and the vertical y-axis ranging from -4 to 5.
### Key Features of the Graph:
- **Curve Description**:
- The curve is a red line that starts from the left at (approximately) (-4, -4), moves smoothly upward, passing near the origin (0, 0), and rises steeply as it progresses to the right.
- **X-Axis and Y-Axis Intersections**:
- The graph approaches but never touches the x-axis as \( x \) goes to negative infinity, indicating a horizontal asymptote at \( y = 0 \).
- The curve passes through the point (0, 1), showing that the function evaluates to 1 when \( x = 0 \).
- **Behavior**:
- For \( x < 0 \): The curve descends gradually.
- At \( x = 0 \): The curve intercepts the y-axis.
- For \( x > 0 \): The curve rises sharply, demonstrating exponential growth.
This graph illustrates the exponential growth behavior typical of functions of the form \( y = e^x \), where the rate of increase becomes very rapid as \( x \) moves in the positive direction.
