Hey there, I've been asked to find the intercepts of:

$\displaystyle x^2 + y^2 = 100$

If I were to just set one value to zero, and then solve for the other one, would it still be correct, even in this form?

For example,

$\displaystyle 0^2 + y^2 = 100$

$\displaystyle y^2 = 100$

(take the square root of both $\displaystyle y^2$ and 100 - I don't know the code)

So then y = 10?

Is this the correct way to go about solving for the intercepts here?

Thanks in advance,

P.S. Maybe it's best done by graphing, but how would I determine the domain and range of this?
