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:
for
Answer:
(3,2)
Step-by-step explanation:
2x+3y=12
substitute x with 3 because x=3
2(3)+3y=12
multiply
6+3y=12
(subtract 6 from both sides)
3y=6
(divide by 3 on both sides)
1y=2
x = 3 and y = 2
