Question
Problem 1. The figure below shows \( f(x) \) and its local linearization at \( x = a \). Note that I have already provided you with the linear approximation. Also note that the \( y \)-axis scale goes by ones.

1. What is the value of \( a \)?
2. What is the value of \( f(a) \)?
3. Is the approximation an under- or overestimate?
4. Use the linearization to approximate \( f(1.2) \).

**Graph Explanation:**

The graph includes a function \( f(x) \) and the line \( y = 2x - 1 \) representing its local linear approximation. 

- The function \( f(x) \) is shown as a curve, and the line \( y = 2x - 1 \) is a tangent approximation at a certain point.
- The x-axis is labeled from 0 to 2, with a specific point noted at \( x = 1 \).
- The y-axis has equal increments, with each unit marked by grid lines.

The curve and the tangent line intersect at a specific point, illustrating the concept of linearization at \( x = a \).
