What is the definition of absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. It is denoted as |x|.

Explain the concept of absolute value inequalities.

Back

Absolute value inequalities express a range of values that a variable can take, based on its distance from a certain point.

Back

x < -1 or x > 13.

Back

It implies that x is within a distance of a from zero, resulting in the compound inequality -a < x < a.

What is the graphical representation of an absolute value function?

Back

The graph of an absolute value function is a V-shape, opening upwards, with the vertex at the point where the expression inside the absolute value equals zero.

Set up two equations: x + 3 = 5 and x + 3 = -5, then solve for x.
