Answer: OPTION C.
Step-by-step explanation:
Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.
For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).
Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.
Therefore, you need to search the option that shown the graph wich contains the point (1,-3).
Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).
This is the graph of the option C.
Answer:
$234
Step-by-step explanation:
First we need to define profits. Profits are Income minus Expenses:
P = I - E
We know profits are $414, so:
414 = I - E
We also can calculate income, as it is equal to price by the sales:
I = p*Q
Here she sold 90 kgs at $7.20 b kg. So:
I = p*Q = 7.20 * 90 = 648
So, replacing in profits equation:
414 = I - E
414 = 648 - E
If we sum E in both sides:
414 + E = 648 - E + E = 648
414 + E = 648
Now, subtracting 414 in both sides:
414 + E - 414 = 648 - 414
E = 234
So, her expenses are $234
