Which parent functions have a range of all real numbers? Select all that apply.
A. Linear
B. Quadratic
C. Absolute value
D. Exponential
E. Square root
F. Cube root

Answer 1

A and F.

- Linear (f(x)=x) has range all real numbers.
- Cube root (f(x)=∛x) also has range all real numbers.

The others do not: quadratic, absolute value, and square root have y ≥ 0; exponential has y > 0.
