Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign. 
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.

<h3>What is compound interest?</h3>
Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it, so that interest is generated the next period on the principal amount plus any accumulated interest. In finance and economics, compound interest is common. 
It is given by formula 
A = 
where:
A is final amount
p is principal amount
r is rate of interest and 
t, is time period
Given: A= $5000, p=$1500, r=2.25% = 0.0225
To find: time period to get compounded amount

Answer:
90°
i went on a whim and guessed it was a right angle, sorry I can't provide reasoning! but it is for sure 90°
Step-by-step explanation:
14x + 5 + 90 = 165
14x + 95 = 165
        -95    -95
14x = 70
/14    /14
x = 5
14(5) + 5 +90 = 165
70 + 95 = 165
165 = 165
