So, the domain of the function f(x) is (∞,∞) Now to find the range, say f(x)= y, which gives x²9=y² or, x= ±√(y²9) Since x is a real number, y²9 must be positive or, y²>9 which gives y ∈ (3,∞),since y>0, which is the required range of f(x) f (x) = 1/√x−5 Now for real value of x5≠0 and x5>0 ⇒ x≠5 and x>5 Hence the domain of f = (5, ∞) And 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 Now we know for this function x5>0 taking square root on bothExample 1 Find the domain and range of the function y = 3 x 2 Graph the function on a coordinate plane The graph is nothing but the graph y = 3 x translated 2 units to the left The function is defined for all real numbers So, the domain of the function is set of real numbers
