<u>D</u><u>e</u><u>f</u><u>i</u><u>n</u><u>i</u><u>t</u><u>i</u><u>o</u><u>n</u>
If we substitute x = 7 in. Answer by using the definition of absolute value. Note that we only substitute x = 7 in x and not -x since 7 is greater than 0 and not less than 0.
You may also be wondering what will happen if we substitute x = any negative numbers.
Because -7 is less than 0. We substitute in -x and not x. This is the definition of absolute value. But to understand it easily, any numbers in absolute value have to equal to their positive value.
Conclusion
- |7| means the absolute value of 7.
- |7| is 7.
- |x| is x when x ≥ 0 but -x when x < 0
