Answer:
Step-by-step explanation:
To find y=mx+b we need to identify two points. I picked (20,45) and (50,65)
From these two points we can find the slope, m.
m=(y2-y1)/(x2-x1)
m=(65-45)/(50-20)
m=20/30=2/3 so now our line is
y=2x/3+b, we can solve for b using either point, I’ll use (20,45)
45=2(20)/3+b
45=40/3+b
b=45-40/3
b=(135-40)/3
b=95/3 so the line is
y=(2x+95)/3
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.
