Question

What is the domain and range of `x=y^2`?

Answer 1

Domain: `x>=0 or [0,oo)` . Range : `y in RR or (-oo,oo)`

Explanation:

`y^2= x or y = +- sqrt x` , Domain: under root should be `>=0`

Domain (Input) : Any real value of `x>=0 or [0,oo)`

Range (output) : Any real value , `y in RR or (-oo,oo)`

graph{x=y^2 [-12.66, 12.65, -6.33, 6.33]} [Ans]
