Question

What is the domain of the function? O all real numbers all real numbers greater than but not equal to 0 all real numbers less than or equal to O O all real numbers greater than or equal to 0

Answer 1

Given expression is

$f(x)=\frac{4}{5}\sqrt[]{x}$

So, from above expression we can see that x is in square root. So, terms inside square root will always be positive.

So, domain of x will be positive.

So, interval of domain will be

$(0,\infty)$

that is real number greater than zero.
