Answer:
Only one extreme value of f(x) is possible.
Step-by-step explanation:
We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)
Now. the condition for extreme values of f(x) is
Hence, differentiating both sides of equation (1) with respect to x, we get
= 0
⇒ x = 3.5.
So there is only one value of x for which f(x) has extreme value which is x = 3.5.
Therefore, only one extreme value of the given function is possible. (Answer)
Answer:
A. Total Money Contributed after n months =
B. Total Money Contributed after 24 months =
Step-by-step explanation:
Given:
Initial contribution =
each month contribution =
After 1 month contributed =
Solving for Part A
let n be the number of months
∴ Total Contribution after n months = Initial contribution + (each month contribution Number of months =
Solving for Part A
Now n= 24 months
∴ Total Contribution after 24 months =
