See explanation Domain The domain of a function is the largest subset of RR for which the function's formula is defined Given function is a polynomial, so there are no limitations for the values of x This means that the domain is D=RR Range The range is the interval of values which a function takes A quadratic function with a positive coefficient of x^2 takes all values inFigure 3 Domain and range of a function and its inverse When a function has no inverse function, it is possible to create a new function where that new function on a limited domain does have an inverse function For example, the inverse of f ( x) = x \displaystyle f\left (x\right)=\sqrt {x} f (xClick here👆to get an answer to your question ️ Domain and range of f(x) = x 3x 3 are respectively

We have f(x) = (x 2 9)/(x 3) Domain off Clearly f(x) is not defined for x – 3 = 0 ie x = 3 Therefore, Domain (f) = R – {3} Range off Let f(x) = y Then, f(x) = y (x 2 9)/(x 3) = y x 3 = y It follows from the above relation that y takes all real values except 6 when x takes values in the set R – {3} Therefore, Range (f All these are real values Here value of domain (x) can be any real number Hence, Domain = R (All real numbers) We note that that Range f (x) is 0 or negative numbers, Hence, Range = (−∞, 0 Ex 23, 2 Find the domain and range of the following real function (ii) f (x) = √ ( (9 −x^2)) It is given that the function is a real functionFind the Domain and Range f(x)=x^3 The domain of the expression is all real numbers except where the expression is undefined In this case, there is no real number that makes the expression undefined Interval Notation SetBuilder Notation The range is the set of all valid values
