Question

I am practicing for my midterm, I would like to know if my answer is similar.

(only question 2)

**Problem 2.** Suppose that \( f(x) \) is a function that is continuous on the interval \([-3, 3]\). The graph of the derivative of \( f(x) \) on the interval \([-3, 3]\) is given below.

**Graph Description:**
The graph shown is of \( y = f'(x) \). It features several key points:
- Starts at approximately \( y = 0 \) when \( x = -3 \).
- Peaks at \( y = 3 \) around \( x = -2 \).
- Crosses the x-axis at \( x = -1 \).
- Reaches a maximum value of \( y = 4 \) at \( x = 0 \).
- Falls again and crosses x-axis at \( x = 2 \) before ending at \( y = 0 \) when \( x = 3 \).

**Questions:**

1. Given that \( f(-1) = 2 \), find the equation of the tangent line to \( y = f(x) \) at \( x = -1 \).

2. Given that \( f(1) = 9 \), evaluate the following limits, if they exist:
   - (a) \( \lim_{x \to 1} f(x) \)
   - (b) \( \lim_{x \to 1^+} f'(x) \)
   - (c) \( \lim_{x \to 1^-} f'(x) \)
   - (d) \( \lim_{x \to 1} f'(x) \)

3. Does \( f'(1) \) exist? Give a brief (one-sentence) explanation.

4. Does \( y = f'(x) \) satisfy the assumptions (hypothesis) of the Intermediate Value Theorem on \([-3, 3]\)? Give a brief (one-sentence) explanation.

**Problem 3.** Let \( k \) be an unknown constant. Consider the function

\[
f(x) = 
\begin{cases} 
k^2 x - 1 & x > 1 \\ 
x^2 + 5 & x \leq 1 
\end{cases}
\]
