Question

The domain of y = x2 is

Answer 1

Domain is all real Numbers

Range is all numbers over 0 - (0, ∞ )

Explanation:

One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from

( − ∞ , ∞ )

For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.

in this situaltion we found that the vertex is at the the origin at (0,0)

therefore the range is (0, ∞ )

I hope this helped. I am sorry if you get this wrong.

Answer 2

all real values

Explanation:

y = x^2

The domain is the possible input values

X can be any value so the domain is all real values of x
