How do you find the domain and range for #h(x)=x^2+2#?

Answer 1

An explanation is given below.

#h(x)=x^2+2#
Note all polynomials have domain as All Real Numbers. In the interval notation it is #(-oo,oo)#
Graph of #h(x)# would be a parabola with vertex at #(0,2)#
The coefficient of #x^2# is positive therefore, the graph opens up.
This graph would have a minimum value of #2#

The maximum value is not known.

Therefore the range is #(2,oo)#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
