we are given
For finding inflection point, we will find second derivative
now, we can find derivative again
now, we can set it to 0
and then we can solve for x
we get
we know that inflection point is a point where concavity changes
so, we will draw a number line and locate x=-7/4
and then we can find sign of second derivative on each interval
Concave up interval:
Concave down interval:
Since, concavity changes at x=-7/4
So, there will be inflection point at x=-7/4
now, we can find y-value
So, the inflection point is

Answer:
The expression represents the total amount of money Mike earned for both weeks is 2.05x dollars
Solution:
Given that, Mike earned x dollars the first week of his new job
He earned 5% more the second week than the first week
To find: Total amount earned in both weeks
From given,
Amount earned in first week = "x" dollars
Amount earned in second week = 5 % more than first week
Therefore,
Amount earned in second week = x + 5 % of x
Thus amount earned in second week = 1.05x dollars
The total amount earned in both weeks:
Total amount = Amount earned in first week + Amount earned in second week
Thus the expression represents the total amount of money Mike earned for both weeks is 2.05x dollars
