Question

What is the domain and range for `y = 2x^3 + 8`?

Answer 1

Domain: `x=`all real numbers
Range: `y=`all real numbers

Explanation:

There are no divisions or square roots, so `x=`all real numbers.

Since it is a positive `x^3` function, `y`'s end behavior is down and up, so `y=`all real numbers.
