Math Problem Statement

Which of the following is the graph of f(x) + 3 = |x + 2|

Solution

To determine the graph of f(x)+3=x+2f(x) + 3 = |x + 2|, let’s analyze the equation step by step:

Step 1: Simplify the equation

The equation can be rewritten as:

f(x)=x+23f(x) = |x + 2| - 3

Step 2: Analyze the components

  1. The base graph is x+2|x + 2|, which is the absolute value function shifted 2 units to the left compared to x|x|.
  2. Subtracting 3 from x+2|x + 2| shifts the graph down by 3 units.

Step 3: Key points of the graph

  • The vertex (where x+2=0|x + 2| = 0) is at x=2x = -2, giving f(2)=3f(-2) = -3.
  • For x>2x > -2, x+2=x+2|x + 2| = x + 2, so f(x)=(x+2)3=x1f(x) = (x + 2) - 3 = x - 1.
  • For x<2x < -2, x+2=(x+2)|x + 2| = -(x + 2), so f(x)=(x+2)3=x5f(x) = -(x + 2) - 3 = -x - 5.

Step 4: Shape of the graph

  • The graph has a V-shape with its vertex at (2,3)(-2, -3).
  • The left branch has slope 1-1, and the right branch has slope 11.

Step 5: Matching the graph

  • Look for a graph with:
    • A vertex at (2,3)(-2, -3),
    • Slope 1-1 to the left of x=2x = -2,
    • Slope 11 to the right of x=2x = -2.

If you provide options or a specific image, I can confirm which graph matches.
