Answer: y= 2x-8
Step-by-step explanation:
2y-4x=-16
2y=-16+4x
y=-8+2x
y= 2x-8
2x + 9 = 43 This is the equation.
2x = 34 Subtract 9 from both sides.
x = 17 Divide both sides by 2.
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.
