What is the range and domain of functions in NCERT Chapter 1?
Answer (1)
In NCERT Class 12 Maths Chapter 1, the domain and range of a function describe its input and output values:
- Domain: The set of all possible input values (x) for which the function is defined. Example: For f(x)=1/x, the domain is all real numbers except x=0.
- Range: The set of all possible output values f(x). Example: For f(x)=x2, the range is [0, infinity) because squares are always non-negative.
