Transcribed Image Text:### Graph and Limits of \( y = f(x) \)
#### The graph of \( y = f(x) \) is pictured below:
(Include the provided graph image here on the website for reference)
**Graph Description:**
The graph shows a function \( f(x) \) plotted on the Cartesian plane with:
- The x-axis ranging from -5 to 5.
- The y-axis ranging from -5 to 5.
- Key points and behaviors of the function:
- There is a jump discontinuity at \( x = 3 \):
- As \( x \) approaches 3 from the left, \( f(x) \) is approaching 4.
- As \( x \) approaches 3 from the right, \( f(x) \) is approaching -4.
- There is an asymptote at \( x = -1 \):
- The function approaches \( \infty \) as \( x \) approaches -1 from both the left and the right.
**Problems:**
(a) Find \( \lim_{x \to -1} f(x) \).
(b) Find \( \lim_{x \to 3^-} f(x) \).
(c) Find \( \lim_{x \to 4} f(x) \).
(d) Find \( \lim_{x \to -4} f(x) \).
(e) Find \( \lim_{x \to -1^-} f(x) \).
(f) Find \( \lim_{x \to -1^+} f(x) \).
(g) Sketch the graph of the derivative \( y = f'(x) \).
**Visual Details of the Graph:**
1. For \( x < -1 \), the function \( f(x) \) is increasing until it reaches an asymptotic behavior at \( x = -1 \).
2. For \( -1 < x < 3 \), the function shows different behaviors. Notably:
- Near \( x = 0 \), \( f(x) \) reaches a local maximum approximately at \( y = 0 \).
- Between \( x = 1 \) and \( x = 2 \), the function exhibits a steep descent and then rises again.
3. At \( x = 3 \), there is a distinct jump discontinuity:
- The left-hand limit (\( x \to 3^- \)) reaches
