Question

find the domain and range of the function f(x)=x^3​

Answer 1

Answer:

Domain and Range both are R(The set of real numbers)

Step-by-step explanation:

Domain is the set of all values which can be put in the function...

here... f(x) = x³

Any number can be cubed...

So the domain is The Real numbers

The range is the set of all values which can 'come out' of the function...

for ANY given number 'y' we can find a REAL x such that

f(x) = x³= y

Hence the domain is The Real numbers

NOTE:- I am assuming that you are talking about real functions...Otherwise the domain and range is the entire complex plain.....C
