I know Bartleby has a limit on three parts, so if you have to only do three, please show me how to do A, B, and D. Thank you.

### Understanding Function Values and Limits Using a Graph

This exercise encourages students to use the provided graph to determine whether specific function values and limits exist. If they do, they are expected to find the values; if not, students should explain why.

#### Questions:

(a) \( f(1) \)

(b) \( \lim_{{x \to 2}} f(x) \)

(c) \( f(4) \)

(d) \( \lim_{{x \to 4}} f(x) \)

#### Graph Analysis:

In the provided graph:

- The \( x \)-axis ranges from -1 to 6.
- The \( y \)-axis ranges from 0 to 6.
- There appears to be a function \( f(x) \) graphed along the coordinate system, depicted as a curve.

### Detailed Explanation of the Graph:

- For \( x = 1 \), locate the corresponding \( y \)-value on the function's curve.
- For \( x \to 2 \), determine the limit of \( f(x) \) by observing the behavior of the function as it approaches \( x = 2 \) from both the left-hand and right-hand sides.
- For \( x = 4 \), assess the function's value directly on the curve.
- For \( x \to 4 \), determine the limit by observing how the function behaves as \( x \) approaches 4 from both sides.
  
Students should pay close attention to any breaks, holes, or discontinuities in the graph, as these often indicate where certain values or limits may not exist. When a function value doesn't match its limit at a particular point, it often suggests a discontinuity at that point.
