Question

What is the domain of f(x) = 3√x? all real numbers positive numbers and zero all integers whole numbers

Answer 1

All real numbers positive numbers and zero.

Explanation:

Domain: set of all possible input values (x-values)

Range: set of all possible output values (y-values)

Given function:

`f(x)=3 √(x)`

As the square root of x is undefined for negative real numbers, the domain is positive numbers and zero.

The largest value of the domain is unbounded, so the domain in interval notation is [0, ∞).

Answer 2

• B. positive numbers and zero

Explanation:

This is a square root function:

• f(x) = 3√x

The domain is the x-values which include all non-negative real numbers

Correct choice is B
