Help with functions and domains?
so I need to find the domain of y= x² + 4 and I need the steps on how to approach it and I need it in "set builder notation." Thanks in advance!

domain means set of values, the 'x' variable can take.
x cannot take values which will make
1) denominator = 0
2) the quantity under square root sign as negative.
so what can u say about your x? which values it cannot take ?
So is it that is can take anything? (I'm sorry if that sounds really stupid. I was put in a high math class suddenly and I'm panicking since I have no idea what we're supposed to be reviewing XD)
you are correct!
since there is no denominator or square toot sign, your 'x' can take ANY REAL VALUE :)
now do u know how to write this in set builder notation ?
