$\large\color{midnightblue}{  q(x)=(x-5)^3    }$

Domain can be any real number, and Range can be any real number as well, because `x-5` isn't raised to an even power, and there is no square root or any other thing that would cause some range restrictions.

You just need to re-word the domain/range.

When you say that all real numbers fit, you are saying that all real positive and all real negative numbers fit for domain/range.
all negative numbers are written as -∞ in interval notation and all positive real numbers are  written as ∞ in interval notation.
