Determine the inverse function
Replace f(x) with y
Swap the positions of x and y
Multiply both sides by -2
Square both sides
Make y the subject
The inverse has been solved. So, we need to replace y with f'(x)
Next, is to determine the interval
Change inequality to 
Hence, the inverse function is:

Answer:
Rate = 1.125
New Value = 312,750
Step-by-step explanation:
A. 1/8 = 0.125
1+0.125=1.125
1.125 x Old value = New Value
B.
1.125 x 278,000 = New Value
312,750

Step-by-step explanation:
Answer:
20 lemons
Step-by-step explanation:
Let the number of lemons = 'x'
85% of x = 17
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1
at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c
c = -1 -1
c = - 2
equation:
y = -x -2
y + x = -2 or - x - y = 2
