Math Problem Statement

Use graphing technology to find the range of the function f, of, x, equals, vertical bar, x, plus, 4, vertical bar, plus, 2, .f(x)=∣x+4∣+2.

Solution

The graph of f(x)=x+4+2f(x) = |x + 4| + 2 shows that the function reaches a minimum value of 2 at x=4x = -4. Since the function is based on an absolute value, it increases in both directions away from this point.

Range of the Function:

  • Minimum value: f(4)=2f(-4) = 2.
  • As xx \to \infty or xx \to -\infty, f(x)f(x) increases without bound.

Thus, the range of the function is: [2,)\boxed{[2, \infty)}

Tip: Absolute value functions always have a V-shaped graph, and their range is determined by their lowest point (if it exists).
