Answer:
The Answer is 0.04
Step-by-step explanation:
The function
is a quadratic function due to the highest exponent being 2.
Given functions are:
![u(x)=-x+3x^{2} -8](https://tex.z-dn.net/?f=u%28x%29%3D-x%2B3x%5E%7B2%7D%20-8)
![v(x)=2x^{2} +8x^3+9x](https://tex.z-dn.net/?f=v%28x%29%3D2x%5E%7B2%7D%20%2B8x%5E3%2B9x)
![y(x)=x^{2} +3x^5+4](https://tex.z-dn.net/?f=y%28x%29%3Dx%5E%7B2%7D%20%2B3x%5E5%2B4)
![z(x) =7x^{2} +2x^3-3](https://tex.z-dn.net/?f=z%28x%29%20%3D7x%5E%7B2%7D%20%2B2x%5E3-3)
<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.
![u(x)=-x+3x^{2} -8](https://tex.z-dn.net/?f=u%28x%29%3D-x%2B3x%5E%7B2%7D%20-8)
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.

According to his calculations, b has a 3/10 chance to win
Answer:
7
Step-by-step explanation:
f(x) = 2x^3 + x^2 − 3x + 1
f'(x) = 6x^2 + 2x − 3
The slope at -2:
f'(-2) = 6(-2)^2 + 2(-2) − 3
f'(-2) = 24 + -4 − 3
f'(-2) = 17
-----
The slope at 0:
f'(0) = 6(0)^2 + 2(0) − 3
f'(0) = − 3
The average rate of change is (17+(-3))/2, or 14/2, or 7
