All Real numbers is your Domain and Range.
Your domain is all the x-values that satisfy your equation. Since all numbers out to infinity can be placed into the x-value, then your domain is all real numbers.
Your range is how far your y-value can get up to. Since you can put up to infinity into your x-value then your y-value can also equal infinity. Therefore, your range is also all real numbers.
In cause you didnt know what all real numbers means.... All real numbers means every single number there is. So... all the decimals, all the fractions, all the negative and positive numbers, all numbers in existence.
