The continuous and differentiable function where f(x) is decreasing at x = −5 f(x) has a local minimum at x = −2 f(x) has a local maximum at x = 2 is given as: y = 9x - (1/3)x³ + 3.
What is a continuous and differentiable function?The continuous function differs from the differentiable function in that the curve obtained is a single unbroken curve in the continuous function.
In contrast, if a function has a derivative, it is said to be differentiable.
What is the solution to the problem above?It is important to note that a function is differentiable when x is set to a if the function is continuous when x = a.
Given the parameters, we state that
f'(5) < 0; and
x = -5
The local minimum is given as:
x = -3;
the local maximum is given as
x = 3
Thus, x = -3 ; alternatively,
x = 3. With this scenario, we can equate both to zero.
Hence,
x + 3 = 0;
3-x = 0.
To get y' we must multiply both equations to get:
y' = (3-x)(x + 3)
y' = 3x + 9 - x² - 3x
Collect like terms to derive:
y' = 3x - 3x + 9 - x²; thus
y' = 9-x²
When y' is integrated, the result is
y = 9x - (x³/3) + c
Recall that
F (-5) < 0
This means that:
9 x -5 - (-5³/3) + c < 0
⇒ -45 + 125/3 + c <0
⇒ -10/3 + c < 0
Collecting like terms we have:
c < 10/3; and
c < 3.33
Substituting C into
f(x) = 9x - x³/3 + c; we have
f(x) = 9x - x³/3 + 3, which is the same as y = 9x - (1/3)x³ + 3.

The participant for the running event is expected to reach more than 1000 in various categories. You decided to use hashing function method to store the information for each participant's BIB number in the hash table.
To begin the problem solving, suppose that 10 registered runners need to be stored. The sample BIB number of the runners are: 101, 102, 103, 104, 107, 111, 121, 217, 157, and 185. Apart from BIB number, participant information also contains a name (string), category (int) -e.g., men open (1), women open (2)), and runtime (int). The default value for runtime is 0 (represent 0 minutes).
Suppose that a linked list is used as
a data structure for the hash table, create a program that a. Implement the hashing functions for this problem. You can accept up to 10 inputs from the user or read from a formatted text file of participant information.
