f(x)=4x and g(x)=cube of √x

Step 2 of 2 : Find the formula for (f/g)(x) and simplify your answer.

Then find the domain for (f/g)(x).

(f/g)(x)=???

Domain=???

## 1 Expert Answer

So f(x) = 4x and g(x) = the cube root of x

__f(x)__ = __4x __ = 4x^{1 - 1/3} = 4x^{2/3}

g(x) x^1/3 or x raised to the one-third power

The domain will be all real numbers.

Trying to understand g(x) in your question- Do you mean there is ( ) around radical x and you have an exponent 3 outside the ( ) ? or Do you see an index of 3 for the radical x ?( we read that as cube root of x)04/10/21
