Math Problem Statement

Berdasarkan grafik tersebut tentukanlah lim x→1+ f(x)

Solution

The problem asks us to evaluate the right-hand limit of the function f(x)f(x) as x1+x \to 1^+ using the given graph. Here's how we can approach it:

  1. Examine the graph near x=1x = 1:

    • From the graph, as xx approaches 1 from the right (x1+x \to 1^+), the function appears to approach the value of 2-2.
    • There is an open circle at (1,2)(1, -2), indicating that f(1)f(1) is not defined or has a different value. However, the right-hand limit concerns what the function approaches, not the actual value at 1.
  2. Conclusion:

    • The right-hand limit of f(x)f(x) as x1+x \to 1^+ is 2-2.

Thus, limx1+f(x)=2\lim_{x \to 1^+} f(x) = -2.

Would you like a detailed explanation of how limits work or have any other questions?

Here are 5 related questions to deepen your understanding:

  1. What is the definition of a one-sided limit?
  2. How do open and closed circles on a graph affect the limit of a function?
  3. How would the left-hand limit limx1f(x)\lim_{x \to 1^-} f(x) be evaluated from this graph?
  4. Can a function be continuous if a limit exists but the function value at that point is different or undefined?
  5. What would change if the limit asked for limx1f(x)\lim_{x \to 1} f(x), rather than the right-hand limit?

Tip: Always check both left-hand and right-hand limits to determine if a function has a two-sided limit!
