Question

8. f, g and h are three functions defined from R to R as follows:
(i) f(x) = x?
(ii) g(x) = x^2 +1 (iii) h(x) = sin x
Then, find the range of each function.​

Answer 1

Step-by-step explanation:

range of

I. f of x can be defined for any real value of x

so range is (-infinity, +infinity)

ii. g of x can be defined for any value of x

and due to x^2 is is always positive which means the least value if g of x must be 1 and then goes on

range =[1,+infinity)

iii. h of x can only value upto 1 and the minimum value can be -1

range=[-1,+1]

hope it is clear
