The function 
is a quadratic function due to the highest exponent being 2.
Given functions are:
<h3>What is a quadratic function?</h3>
A function of the form 
with 
is called a quadratic function means the highest exponent of polynomial should be 2.
Let us check one by one.
Highest exponent =2
The function is also of form so u(x) is a quadratic function.
The functions v(x), y(x), and z(x) are having highest exponents as 3,5, and 3 respectively so they are not quadratic functions.
Hence, the function is a quadratic function due to the highest exponent being 2.
