Identify the given function as a linear function, a quadratic function, or a rational function.
-$$f ( x ) = \frac { x ^ { 2 } - 16 } { x ^ { 2 } + 9 x + 20 }$$
A) Quadratic
B) Rational
C) Linear

Question

Quizplus · Accepted Answer

The function is a rational function because it has a polynomial in the numerator and denominator with a non-zero coefficient of the highest degree term being non-zero.

Identify the Given Function as a Linear Function, a Quadratic f(x)=x2−16x2+9x+20f ( x ) = \frac { x ^ { 2 } - 16 } { x ^ { 2 } + 9 x + 20 }f(x)=x2+9x+20x2−16​
