Paano Kalkulahin si Domain and Range
Ano ang Domain and Range?
The domain of a function is the complete set of input values (x) for which the function is defined and produces a real output. The range is the complete set of output values (y). Identifying domain and range restrictions is a fundamental skill in algebra and calculus — it determines where functions are valid and where operations such as integration or root-finding apply.

Step-by-Step na Gabay
- 1√(expression): domain requires expression ≥ 0
- 2ln(expression): domain requires expression > 0 (strictly positive)
- 31/expression: domain excludes values where expression = 0
- 4Linear ax+b: domain is all real numbers (−∞, +∞)
- 5Composite functions: apply restrictions at each step
