Answer:
Approximation f(25.3)=5.03 (real value=5.0299)
The approximation can be written as f(x)=0.1x+2.5
Step-by-step explanation:
We have to approximate 
with a linear function.
To approximate a function, we can use the Taylor series.
The point a should be a point where the value of f(a) is known or easy to calculate.
In this case, the appropiate value for a is a=25.
Then we calculate the Taylor series with a number of terms needed to make a linear estimation.
The value of f'(a) needs the first derivate:
Then
We evaluate for x=25.3
If we rearrange the approximation to be in the form mx+b we have:
Then, m=0.1 and b=2.5.
X^2 + 2x - 35
(a x b) = -35
(a + b) = 2
(7 x -5) = -35
(7 + -5) = 2
Plug them in:
x^2 - 5x + 7x -35
x(x - 5) + 7(x - 5)
Therefore, you can conclude that our final answer is...
(x + 7)(x - 5)

Answer:
Function p is a quadratic function
Step-by-step explanation:
I personally googled a what each of the drop downs, and a quadratic function looked very similar to the image.
Our experience with students bringing cell phones and entertainment systems to school has been that too often they go missing (lost or stolen) either in school or on the bus. This creates many issues regarding questioning students and investigating incidents. We feel it is the safest policy for students not to have them in school. As our sites are small, everyone has the ability to make and receive calls to their parents in an emergency. We also feel it can lead to miscommunication if students are being communicated to directly and administration or staff is not also informed.
This should be good
