Question

Transcribed Image Text:The image presents four distinct graphs labeled A, B, C, and D.
**Graph A:**
- Features a piecewise linear function with a discontinuity at \( x = 3 \).
- As \( x \) approaches 3 from the left, the graph appears to descend towards the point with a missing value represented by an open circle.
- The horizontal axis (x-axis) ranges from approximately -5 to 5, and the vertical axis (y-axis) ranges similarly.
- The limit of \( f(x) \) as \( x \) approaches 3 from the graph is to be determined and filled in the provided box: \(\lim_{x \to 3} f(x) = \).
**Graph B:**
- Depicts another piecewise function with a sharp turn at \( x = 3 \).
- As \( x \) approaches 3, the function seems to have a jump discontinuity, with two distinct y-values at this point: an upper value assigned to the left approach and a lower value to the right.
- The limit of \( f(x) \) as \( x \) approaches 3 is to be calculated and filled in the empty box: \(\lim_{x \to 3} f(x) = \).
**Graph C:**
- A piecewise linear graph with an apparent gap at \( x = 3 \).
- The left-hand limit and right-hand approach to this x-value suggest differing endpoint values, indicated by open circles.
- The limit of \( f(x) \) as \( x \) approaches 3 here is to be solved and noted in the blank space: \(\lim_{x \to 3} f(x) = \).
**Graph D:**
- Presents a piecewise function, similar to the others, with an evident step or change at \( x = 3 \).
- Both sides of \( x = 3 \) appear to join smoothly indicating a possible value at this point.
- The observer is tasked to deduce and write the limit of \( f(x) \) as \( x \) approaches 3 in the provided space: \(\lim_{x \to 3} f(x) = \).
Each graph includes essential components for visualizing and determining the limit of \( f(x) \) as \( x \) nears the point of interest, making them valuable educational tools for exploring continuity and limits in functions.
