WebbWhen using interval notation, domain and range are written as intervals of values. For f (x) = x 2, the domain in interval notation is: D: (-∞, ∞) D indicates that you are talking about the domain, and (-∞, ∞), read as negative infinity to positive infinity, is another way of saying that the domain is “all real numbers.”. WebbWrite your answer in interval notation: [ −6, 3) [ - 6, 3) Example: Solving a Compound Inequality with the Variable in All Three Parts Solve the compound inequality with variables in all three parts: 3+x >7x−2 > 5x−10 3 + x > 7 x − 2 > 5 x − 10. Show Solution Try It Solve the compound inequality: 3y <4−5y < 5+3y 3 y < 4 − 5 y < 5 + 3 y.
