Transcribed Image Text:The image presents two graphs labeled b) and c), each depicting mathematical functions with vertical asymptotes.
### Graph b) Description:
- **Axes:** The horizontal axis (x-axis) ranges from -10 to 10, and the vertical axis (y-axis) appears unmarked.
- **Function Behavior:** The graph shows a curve that approaches a vertical line (asymptote) near x = 0 from both sides. As x approaches zero from the left, the function decreases without bound. As x approaches zero from the right, the function increases without bound. The function appears to have a discontinuity at x = 0.
### Graph c) Description:
- **Axes:** The horizontal axis (x-axis) also ranges from -10 to 10, similar to graph b).
- **Function Behavior:** This graph shows two vertical asymptotes, one near x = -5 and another near x = 5. As x approaches -5 from the left, the function increases steeply, and as x approaches -5 from the right, it decreases steeply. Similarly, near x = 5, the function decreases steeply as x approaches from the left and increases steeply from the right. There is a marked trough between these asymptotes.
Both graphs illustrate functions with distinct vertical asymptotes and overall behavior at those asymptotes.

Transcribed Image Text:The text in the image is a mathematical problem that reads:
"Given that \( f'(x) = -\frac{8}{(x-1)^2} \), which of the following graphs could be the graph of \( f(x) \)?"
The image shows one graph labeled "a)".
**Graph Description:**
- The graph is of a function that involves two asymptotic behaviors.
- There is a vertical asymptote at \( x=1 \), where the curve appears to approach but never touches this line. The curve dips steeply downwards on both sides of this asymptote.
- To the left of the asymptote (for \( x < 1 \)), the graph drops steeply and continues decreasing as it approaches from the left.
- To the right of the asymptote (for \( x > 1 \)), the graph rises steeply and then continues upward as it moves to the right.
- The function appears to resemble a hyperbola centered around the vertical asymptote.
- The horizontal asymptote seems to be at \( y = 0 \) as the function heads towards both the negative and positive directions of the x-axis.
