Question

What are the domain and range of the function? f(x) =2√x​

Answer 1

Explanation:

x cannot be a negative value which implies the values of x that satisfy the condition are [0,∞].

So the domain of the function is [0,∞].

The minimum of the function is when x=0, so the minimum will be f(x)=2(0)=0.

This implies the range of the function is [0,∞].
