Let the function be represented by f(x).
Multiplying the number x by 4 results in 4x. Subtracting 2 from results give 4x - 2. So the function becomes:
f(x) = 4x - 2
Finding the inverse function:
Replace f(x) by y, and isolate x on one side of the equation and find the inverse:
Yes the inverse function represents the reverse process. Original function involved multiplication by 4 and then subtraction of 2. Inverse function involves addition of 2 and then division by 4. So the inverse represents the reverse of the given process.
For this case we have,
- store 1:
3/4 of a bushel of apples -----------------------> $ 9
1 bushel of apples -------------------------------> x
From here the value of x is cleared, resulting in:
- store 2:
2/3 of a bushel of apples -----------------------> $ 9
1 bushel of apples -------------------------------> x
From here the value of x is cleared, resulting in:
Therefore it is convenient to buy apples in store 1 because it is cheaper.
Answer:
It is convenient to buy apples in store 1 because it is cheaper. A division must be made for each case because you want to find the unit cost of a product having the total cost and the amount in fraction.
