Question

How do you find the domain and range of `g(x)=sqrtx+7`?

Answer 1

Domain: `x >= 0 or [0 ,oo)` . Range : `g(x) >=7 or [7 , oo)`

Explanation:

`g(x) = sqrt(x) +7`. Domain: under root should be `>=0 :. x >= 0`
Range : `g(x) >=7`

Domain: `x >= 0 or [0 ,oo)` . Range : `g(x) >=7 or [7 , oo)` graph{x^0.5 +7 [-40, 40, -20, 20]} [Ans]
