The range of the relation R={(x, y):x,y€ All real numbers and y=x^2+1 is A)all real numbers B) (1, Infinity) C)[1, Infinity) D)(-infinity,1] ?

The range of the relation R is the set of all possible y-values that can be obtained from the given equation y = x^2 + 1.

To find the range, we need to consider the possible values of y. Since x can be any real number, we can see that as x increases or decreases, the value of x^2 + 1 also increases. Therefore, there is no upper limit to the values of y.

However, the minimum value of x^2 + 1 is 1 (when x = 0). Therefore, the range of the relation R is [1, Infinity).

So, the correct answer is C) [1, Infinity).
