I assume the answer your class is looking for is a domain of “all real numbers” but there are many possible answers that each effect what your range would be, any subset of the complex numbers can be chosen as the domain (also there may be more se.

For example f(x) always gives a unique answer, but g(x) can give the same answer with two different inputs (such as g(-2)=4, and also g(2)=4). If the function is math\frac 32 - x^2/math, then like others have pointed out — the maximum exists for mathx=0/math and there is no lower bound. And by definition of domain - The domain is where the function is not defined.

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 2.3, 2 Find the domain and range of the following real function:.

For the reciprocal squared function latexf\left(x\right)=\frac{1}{{x}^{2}}/latex, we cannot divide by latex0/latex, so we must exclude latex0/latex from the domain. Domain refers to all those values of X are particularly real values of X that it can take such that the value of the function comes out to be a particularly defined real number:. We need to establish the minimum while recognizing there is no maximum.

Considering the last thread was so incredibly helpful I decided to post yet again. In this case, there is no real number that makes the expression undefined.
