Answer:
Hence, the given statement that:
The equation of a rational function does not have to contain a rational expression is a False statement.
Explanation:
In mathematics, a rational function is any function which can be defined by a rational fraction, i.e. an algebraic fraction such that both the numerator and the denominator are polynomials. Although the coefficients of these polynomials may not be rational numbers.
Hence, the statement:
The equation of a rational function does not have to contain a rational expression is FALSE.
