f, g and h are th

Answer :

(i) f: R R such that f(x) = x2

Since the value of x is squared, f(x) will always be equal or greater than 0.


the range is [0, ∞)


(ii) g: R R such that g(x) = x2 + 1


Since, the value of x is squared and also adding with 1, g(x) will always be equal or greater than 1.


Range of g(x) = [1, ∞)


(iii) h: R R such that h(x) = sin x


We know that, sin (x) always lies between -1 to 1


Range of h(x) = (-1, 1)
