Math Problem Statement

Solution

It looks like you're working on sketching a function that satisfies a set of limit conditions and discontinuities. I'll guide you step by step on how to construct this graph.

Key Features to Include in the Graph:

  1. Asymptotes

    • Draw a dashed vertical asymptote at x=6x = -6, since limx6f(x)=\lim\limits_{x \to -6} f(x) = \infty.
    • Draw a dashed horizontal asymptote at y=1y = 1, since limxf(x)=1\lim\limits_{x \to -\infty} f(x) = 1.
  2. Discontinuities and Limits

    • Jump discontinuity at x=1x = -1

      • limx1f(x)=3\lim\limits_{x \to -1^-} f(x) = 3, meaning as xx approaches 1-1 from the left, f(x)f(x) is close to 33.
      • limx1+f(x)=2\lim\limits_{x \to -1^+} f(x) = -2, meaning as xx approaches 1-1 from the right, f(x)f(x) is close to 2-2.
      • f(1)=0f(-1) = 0, so we plot the point (1,0)(-1, 0).
    • Infinite discontinuity at x=3x = 3

      • limx3f(x)=2\lim\limits_{x \to 3^-} f(x) = 2 and limx3+f(x)\lim\limits_{x \to 3^+} f(x) does not exist (which likely means it heads toward ±\pm \infty).
    • Removable discontinuity at x=7x = 7

      • limx7f(x)=1\lim\limits_{x \to 7^-} f(x) = 1, but f(7)=4f(7) = 4, so there is a hole at (7,1)(7,1) and a point at (7,4)(7,4).
  3. Other Key Points and Behavior

    • f(1)=0f(1) = 0 → The function crosses the x-axis at (1,0)(1,0).
    • limxf(x)=\lim\limits_{x \to \infty} f(x) = \infty, meaning the function increases indefinitely as xx \to \infty.

How the Graph Looks:

  • The leftmost part of the function approaches the horizontal asymptote y=1y = 1.
  • A jump discontinuity at x=1x = -1 from y=3y=3 to y=2y=-2.
  • The function moves through (1,0)(-1, 0) and (1,0)(1,0), with an increasing trend.
  • At x=3x = 3, there is an infinite discontinuity, meaning a vertical asymptote.
  • At x=7x = 7, there is a removable discontinuity, with a hole at (7,1)(7,1) and a separate point at (7,4)(7,4).
  • As xx \to \infty, the function grows toward infinity.
