What is the standard form of an absolute value function?

The standard form of an absolute value function is represented by the equation y = |x|. In this case, the notation used in the choice indicates the absolute value by using slashes or bars around the variable x. The absolute value function takes any real number input x and returns the non-negative value of that number, effectively removing any negative signs.

This aligns with the behavior of absolute value, where for any value of x, y will always be zero or positive. The graph of this function forms a V-shape, with the vertex at the origin (0, 0). Understanding the concept of absolute value as a measure of distance from zero helps clarify why this specific choice represents the standard form of an absolute value function.
