since the X is squared therefore this is a graph of a parabola,
and the x is positive so it opens up and its vertex is on +2.
And the Domain is: [-infinity, +infinity]

The domain is the real numbers in most cases and the range is
the set of positive reals greater than or equal to 2 since x squared is always positive and the lowest it can be is 0 by making x=0.
So I think first poster is right.

Domain is all real numbers, and range is most likely [2, infinity)

In BODMAS, Multiplication is till now Addition besides, no want for brackets. so the final 2 is greater effective by way of 0 to get 0. Then there are fourteen '2's, making 28, and minus the two is 26. including the 0 for sure continues to be at 26. Tada! XD

Domain (negative infinity, infinity)
Range [2, infinity)

x can take any value
domain is the real line
Range is all positive values on the real line that is grater than or = 2.
square of a number cannot be negative; you're also adding 2 to it.

f(x) = x^2 +2
domain is all real values
range is
[2 , + infinity[
