a way of writing subsets of a real number line.

• Domain

• Range

• Interval Notation

• Piecewise Function

Which parent function is this?

• Quadratic

• Cubic

• Linear

• Rational

Answer explanation

The correct answer is 'Rational' because a rational function is defined as the ratio of two polynomials. This distinguishes it from quadratic, cubic, and linear functions, which have different forms and characteristics.
