Estimating Limit Values from Graphs

AP Calculus AB· difficulty 2/5

x = 1

The graph has a vertical asymptote at x=1x = 1 with the function going to ++\infty on the right and -\infty... wait, see the graph: left side goes to -\infty, right side from ++\infty. What is limx1f(x)\lim_{x\to 1} f(x)?

  • A

    ++\infty

  • B

    Does not exist

  • C

    -\infty

  • D

Explanation

Left and right one-sided limits diverge to opposite infinities, so the two-sided limit does not exist (and is not ±\pm\infty).
