Question

The graph of the function f(x)=4/5 sqrt x is shown.
What is the domain of the function?

Answer 1

D

Explanation:

Answer 2

All real number greater than equal to zero.

Explanation:

The function is given by

`f(x) = (4)/(5)\sqrt x`

The domain is defined as the input values so that the function is well defined.

here, the values of x should be all real number and zero also.

So, the correct option is (d).
