If the domain of a rational functionRis{x|x≠0}thenlimx→2R(x)=? Question: R {x|x≠0} limx→2R(x)=? Direct Substitution: Direct substitution atx=ais a method of solving a limit, and is defined as follows: limx→af(x)=f(a) ...
Domain of a Rational Function: Let's say we have a rational function {eq}\displaystyle f(x) = \frac{p(x)}{q(x)} {/eq}. The numerator of the function is {eq}\displaystyle p(x) {/eq} and the denominator of the function is {eq}\displaystyle q(x) {/...

Domain of a Rational Function with HoleLet y = f(x) be a function. Domain of the above function is all real values of 'x' for which 'y' is defined. If there is any value of 'x' for which 'y' is undefined, we have to exclude that particular value from the set of domain. ...
How do I find the domain of a rational function? To find the domain of a rational function, you need to determine the values of x that make the denominator of the function equal to 0. These values are not included in the domain. The remaining values of x will make up the domain of...
f(x)=√7−xf(x)=7−x is a radical function. The following table gives examples of domain restrictions for several different rational functions. Note that a rational function has the variable present in the denominator. FunctionRestrictions to the Domain f(x)=1xf(x)=1x If x=0x=0, ...
