1. **State the problem:** We need to estimate the value of $k(j(2))$ using the given graphs of $j(x)$ and $k(x)$ for $-1 \leq x \leq 5$.
2. **Find $j(2)$ from the graph of $j(x)$:**
- The graph of $j(x)$ is piecewise linear, rising from $(-1,-1)$ to $(3,5)$.
- At $x=2$, which lies between $-1$ and $3$, the value of $j(2)$ is approximately on the line between $(-1,-1)$ and $(3,5)$.
- The slope of this segment is $\frac{5 - (-1)}{3 - (-1)} = \frac{6}{4} = 1.5$.
- Using point-slope form from $(-1,-1)$:
$$j(2) = -1 + 1.5 \times (2 - (-1)) = -1 + 1.5 \times 3 = -1 + 4.5 = 3.5$$
3. **Find $k(j(2)) = k(3.5)$ from the graph of $k(x)$:**
- The graph of $k(x)$ is an increasing curve approaching 6 as $x$ approaches 5.
- At $x=3.5$, the value of $k(x)$ is approximately between 5 and 6, closer to 5.5.
4. **Conclusion:**
$$k(j(2)) \approx k(3.5) \approx 5.5$$
Thus, the estimated value of $k(j(2))$ is approximately **5.5**.
