Math Problem Statement

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

Solution

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

Step 1: Rewrite the function

We can express f(x)f(x) as: f(x)=x+23f(x) = |x + 2| - 3

Step 2: Understand the transformations

The base function is g(x)=xg(x) = |x|, which is a V-shaped graph centered at the origin.

  1. Horizontal shift: The term x+2x + 2 indicates a shift 2 units to the left.
  2. Vertical shift: Subtracting 3 from the absolute value moves the graph 3 units down.

Step 3: Key points and graph shape

  1. The vertex of f(x)=x+23f(x) = |x + 2| - 3 is at (2,3)(-2, -3).
  2. The graph opens upwards (retains the V shape).
  3. The slope of the arms of the V is 1 and -1, as usual for absolute value functions.

Step 4: Match the graph

Look for a graph with the vertex at (2,3)(-2, -3) and symmetric arms forming a V-shape. The graph should shift 2 units to the left and 3 units downward compared to y=xy = |x|.

Questions to Expand:

  1. How do horizontal shifts affect the graph of other functions, like quadratics?
  2. Why does the slope of the absolute value arms remain constant at 1 and -1?
  3. How does f(x)+k=xf(x) + k = |x| compare when k>0k > 0 or k<0k < 0?
  4. Can this transformation be applied to non-linear functions like g(x)=x2g(x) = x^2?
  5. How can piecewise functions represent absolute value equations?

Tip: Always identify transformations one step at a time to simplify graph analysis!
