Let and g (x) = x be two functions defined in the domain R+ {0}. Find

(fg) (x)

Given: f(x) = √x and g (x) = x two functions defined in the domain R + {0},


To find: (fg)(x)


Explanation: this can be obtained by multiplying functions f(x) and g(x), i.e.,


(fg)(x) = f(x) g(x)


Substituting the corresponding equation, we get


(fg)(x) = (√x)(x)


(fg)(x) = x√x
