Question

Select the correct answer. Which function has a domain of all real numbers?
y = -x + 5 y = -2(3x) ³ O A. B. OC. y = CD. y = (x + 2)² (2x) ³ (2x) - 7​

Answer 1

The function that has a domain of all real numbers is:

A. $y = 2x^{\frac{1}{3}} - 7$.

What is the domain of a function?

The domain of a function is the set that contains all possible input values for the function.

If a function has an even root, equivalent to an exponent of $\frac{1}{n}$ with n even, the domain is only positive values, while if the exponent is odd, the domain is all real values.

Researching the problem on the internet, the function with odd exponent is:

A. $y = 2x^{\frac{1}{3}} - 7$.
