Answer:
True
Explanation:
we know that
A rational function is the ratio of two polynomials, in which the denominator has a degree of at least 1 . In other words, there must be a variable in the denominator.
In this problem we have
The numerator is a linear polynomial (degree 1)
The denominator is a linear polynomial (degree 1)
therefore
The function f(x) is a rational function
The statement is true
