find the domain and range of following ​

{xcR} (x is all real numbers) and {y2+1}

Step-by-step explanation:

1st: Find x by squaring both sides, subtracting 1 from both sides, and dividing by 2 from both sides to get x=

2nd: Plug in x for y=+1 which equals y=2()+1

3rd: This gives you the range (y) which is {y2+1}

4th: domain is all real numbers

I hope this helped because this took me 30 minutes to do. I had to pull out my algebra math book to check I did it right. I hope I was right!
