What is the domain and range of f (x) = 1/x?Find the Domain and Range f (x)= (x1)/ (x1) f (x) = x − 1 x 1 f ( x) = x 1 x 1 Set the denominator in x−1 x1 x 1 x 1 equal to 0 0 to find where the expression is undefined x1 = 0 x 1 = 0 Subtract 1 1 from both sides of the equation x = −1 x = 1 Transcript Misc 5 Find the domain and the range of the real function f defined by f (x) = x – 1 Here we are given a real function Hence, both domain and range should be real numbers Here, x can be any real number Here, f (x) will always be positive or zero 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 positive numbers, So range cannot be negative Hence, Range
