Select all of the following functions that have a range of y ≥ 0.

absolute value.
squaring.
identity.
cubing.
square root.

Answers are choice A, choice B, choice E

The identity parent function, f(x) = x, has the range equal to the set of all real numbers. The same can be said about the cubic parent function g(x) = x^3. This is why we can eliminate choice C and choice D. The other answer choices have a range of non-negative numbers. This is assuming we are talking about parent functions (and not shifts or scalings or dilations of them).
