Identify the given function as a linear function, a quadratic function, or a rational function.
-$$f ( x ) = \frac { 1 } { 5 } x ^ { 2 } - 64$$
A) Rational
B) Quadratic
C) Linear

Question

Quizplus · Accepted Answer

The given function is a quadratic function because it has a degree of 2. The quadratic function is of the form $f(x)=ax^2+bx+c$, where $a$, $b$, and $c$ are constants. In this case, $a=\frac{1}{5}$, $b=0$, and $c=-64$.
