The second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40
<h3>Quadratic equation</h3>
From the question, we are to determine which second-degree polynomial function f(x) has a lead coefficient of 4 and roots 5 and 2
To determine this, we will use the given roots to determine the equation
The roots are 5 and 2
Thus
x = 5 and x = 2
x - 5 = 0 and x - 2 = 0
Therefore,
(x -5)(x -2) = 0
Distributing
x(x -2) -5(x -2) = 0
x² -2x -5x + 10 = 0
x² -7x + 10 = 0
Now, multiplying through by 4, we get
4x² -28x + 40 = 0
Thus, the function becomes f(x) = 4x² -28x + 40
Hence, the second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40

Answer:
9%
Step-by-step explanation:
Count the squares side which is 10
Then Count the bootom side of the square which is 10
10 x 10 =100
Now count how many squares are filled. 9
9/100=9%
For this case we have the following function:

By definition we have that the average rate of change is given by:

We evaluate the function for the given interval:
For x = 0:

For x = 1:

Substituting values we have:

Rewriting we have:
Answer:
the average rate of change from x = 0 to x = 1 is:
