By evaluating the quadratic function, we will see that the differential quotient is:

<h3>
How to get (f(2 + h) - f(2))/h?</h3>
Here we have the quadratic function:

Evaluating the quadratic equation we get:

So we need to replace the x-variable by "2 + h" and "2" respectively.
Replacing the function in the differential quotient:

If we simplify that last fraction, we get:

The third option is the correct one, the differential quotient is equal to 8 + 4.

Answer:it is 18*20 effective every year
Step-by-step explanation:
Answer:
40 minutes.
Step-by-step explanation:
- time spent on the thread mill as a function of d(day) = t(d)
= 30 +2(d-1) minutes
[where d represents day number]
(when d is 1 the time spent should be 30
so substitute d=1 and check it will be 30 only.
on first day he will spend 30 minutes so, I added 30 .
and on every additional day( these additional days are excluding first day), he will increase the time by 2 minutes.so, I added 2(d-1) to initial 30 minutes)
- so, T(6), the minutes he will spend on the treadmill on day 6=
=30+2(6-1)
=30+2(5)
=30+10
=40 minutes
The price of the stock is below its starting price because the price will decrease before it increases
