The minimum value of the function f(x)=|x-4| exists at

The minimum value of the function f(x)=∣x−4∣f(x)=|x-4| exists at

Options

  1. Ax = 0
  2. Bx = 2
  3. Cx = 4
  4. Dx = – 4

Correct answer

C. x = 4

Step-by-step solution

From graphical method: Graph of f(x)=∣x−4∣f(x)=|x-4|
It is clear from the graph, minimum values of f(x)f(x) is 0 at x=4x=4.
