Question

Domain and range of y= square root of x minus 2

Answer 1

Y = the square root of x minus 2 is portrayed in the file attached below.
As you can see, the domain (x value) begins at 2. We can use interval notation to say that the domain is [2, infinity) Infinity because it will stretch out to infinity. While the range will be [0,infinity) (message me if you don't recognize these concepts please.)
