Math Problem Statement

Let F(x) = (x^2 + 3x + 2) / (2 - |x|). Make tables of values of F at values of x that approach c = -2 from above and below. Then estimate lim F(x) as x approaches -2.

Solution

The problem defines the function F(x)=x2+3x+22xF(x) = \frac{x^2 + 3x + 2}{2 - |x|}, and asks to:

  1. Make a table of values for F(x)F(x) as xx approaches 2-2 from both above and below.
  2. Estimate the limit limx2F(x)\lim_{x \to -2} F(x).

Let's first evaluate F(x)F(x) as xx approaches 2-2 from the left (below) and right (above). This will help estimate the behavior of the function around x=2x = -2.

The function involves x|x|, meaning we'll handle values for x|x| differently based on whether xx is positive or negative. For x>0x > 0, x=x|x| = x, and for x<0x < 0, x=x|x| = -x.

Table of Values

We will calculate the values of F(x)F(x) at points slightly above and below 2-2, such as:

  • From below: x=2.1,2.01,2.001x = -2.1, -2.01, -2.001
  • From above: x=1.9,1.99,1.999x = -1.9, -1.99, -1.999

Let me compute those values for you.Here is the table of values for F(x)=x2+3x+22xF(x) = \frac{x^2 + 3x + 2}{2 - |x|} as xx approaches 2-2 from both below and above:

xx (from below)F(x)F(x) (below)xx (from above)F(x)F(x) (above)
-2.1-1.10-1.9-0.90
-2.01-1.01-1.99-0.99
-2.001-1.001-1.999-0.999

Estimating the Limit:

  • As xx approaches 2-2 from below, F(x)F(x) approaches 1-1.
  • As xx approaches 2-2 from above, F(x)F(x) approaches \
