Express the set W={x∣0<x<8} using interval notation.
To express the set W = {x | 0 < x < 8} using interval notation, we can represent the range of x values within W using parentheses and the inequality symbols for open intervals.
In this case, the set W represents all the values of x that are greater than 0 but less than 8. So, using interval notation, we write:
W = (0, 8)
This notation indicates that x is greater than 0 but less than 8, with both endpoints being excluded.
