Using it's definition, it is found that the function f(x) has a point of inflection at:
A. x = 8 only.
<h3>What are the points of inflection of a function?</h3>
- The critical points of a function are the <u>values of x</u> for which:
- Additionally, there has to be a change in the sign of
Researching the problem on the internet, it is found that:
- For 0 < x < 5,
.
- For x = 5, is undefined.
- For 5 < x < 8,
.
- For x = 8, .
- For 8 < x < 12, .
- For x = 12, .
- For 12 < x < 16, .
The two conditions, and a change in the signal of are only respected at x = 8, which is the lone inflection point.

Explanation:
or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Inequalities are used to represent unequal expressions.
The solution set to 
is: 
The inequality is given as:
From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat 
, as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:
