The function f(x) takes two numerical inputs, x and y, and returns their product. The function also takes the absolute value of x and y before multiplying them together. The function is only defined for x and y in the range of [-32, 32]. If you try to input values outside of that range, the function will return an error. The function is mirrored around the y-axis, so if you input a value of x, the function will return the same value of y.
