Question 342312: My math work book says "Write the range and domain of P = {(x,y) / y + x squared}. The range is the domain equals all real numbers and the range equals y :y>0}. I understand the real numbers but can you explain the answer for range? Any assistance would be appreciated! Thank you.

My math work book says "Write the range and domain of P = {(x,y) / y = x^2} }. The domain equals all real numbers and the range equals y :y>0}.
--------------------
I understand the real numbers but can you explain the answer for range?
Any assistance would be appreciated! Thank you.
==================
Yes, the domain is All Real Numbers.
---
When you equare each of these numbers you always get a positive
number except for the square of zero which is zero.
---
So the Range is "All Real Numbers greater than or equal to zero".
