The domain is all real numbers. (-infinity, infinity)
You can put any real number x value into the function.
X=7, y=6. that’s your answer!
X equals 60 because 2x60=120. and 120-10=110
9.This is because it goes through the whole circle passing through the centre point. at the full width
The rest are pretty easy. I'm sure you can manage. Good luck!
First, add 2 to both sides. You should have 3/2x=21. Multiply both sides by 2 which gives you 3x= 42. Divide by 3 and you have x=14
