I have looked up what an elementary function is but I'm still stuck with showing that
y=abs(x) is one.
Can anyone explain how to show this?

The absolute value function, denoted by |x|, is a mathematical function that gives the distance between a number and 0 on a number line. It always returns a positive value.
The absolute value function is represented by the equation y = |x|, where y represents the output or result of the function and x represents the input or value being evaluated.
The graph of the absolute value function is a V-shaped graph, also known as a "V-curve". The vertex of the graph is located at (0,0) and the graph extends infinitely in both the positive and negative directions along the x-axis.
The absolute value of a number can be thought of as its distance from 0 on a number line. It is always a positive value, regardless of whether the original number is positive or negative.
The absolute value function is commonly used in physics and engineering to represent distance, speed, and acceleration. It is also used in economics to represent differences between forecasted and actual values. In everyday life, it can be used to calculate the absolute difference between two numbers, such as measuring how much a stock price has changed.
