For instance, f (x) = The domain is simply the denominator set equal to 0, {xl x≠3} However, range is found by solving for (isolating x to one side) and setting the denominator equal to zero x = So range is {xl x≠0} This is a systematic method that I assume is the only way to find the range 2x 1 = 0 2x = 1 x = 1 / 2 Therefore , Domain = R { 1/2 } All real numbers are used as range here For getting solve the denominator of the given fraction and reduce the value of x from the real number "R" Hope it helps you dude Given f(x) = 1x2 To find the range of function Explanation So, the range of a function consists of all the second elements of all the ordered pairs, ie, f(x), so we have to find the values of f(x) to get the required range Given, f(x) = 1x2 Now for real value of f, x2≥ 0 Adding negative sign, we get Or x2≤ 0 Adding

Find the domain and range of the function `f(x)=(1)/sqrt(x5)`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 There is also no latexx/latex that can give an output of 0, so 0 is excluded from the range as well Note that the output of this function is always positive due to the square in the denominator, so the range To find The domain and range of the real function Solution To find domain Equate the denominator to zero Denominator (3x)=0 x=3 This means at x=3 function is not defined And by definition of domain The domain is where the function is not defined Domain is Range Put f(x)=y Range is the set of value that correspond to domain
