Answer:
1/x+2
Step-by-step explanation:
To find the inverse of the function, try switching the x value with the y value or function value
something like: x=1/g(x)-2
then, just manipulate the equation so that g(x) is by itself again, but this time, since it is an inverse, it's denoted as g-1(x)
x=1/g-1(x)-2
x+2=1/g-1(x)
(g-1(x))(x+2)=1
g-1(x)=1/(x+2)
Answer:
d=1
Step-by-step explanation:
Factor d^2 - 2d - 8 into (d-4)(d+2)
Move -2/d+2 onto the other side, changing it into 2/d+2.
Let the empty side equal zero.
Add 3/d-4 and 2/d+2
Then add that to -3d.
Multiply 0 by d+2 and d-4 to get 2d-2 by itself.
2d=2
d=1
I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
The answer i came up with is 0.68 i don't know if thats what you need or not. hopefully i helped.

P(1) = 37,100
P(4) = 58,400
The linear equation (for x ≥ 1)
P(x) = 37,100 + a(x-1)
For x = 4
58,400 = 37,100 + a(4-1)
58,400 - 37,100 = 3a
21300 = 3a
a = 7100
So, the linear equation:
P(x) = 37100 + 7100*(x-1)
P(x) = 37100 + 7100x - 7,100
P(x) = 7100x + 30000
To find when the profit should reach 108100, we can substitute P(x) by 108100.
108100 = 7100x + 30000
108100 - 30000 = 7100x
78100 = 7100x
x = 78100/7100
x = 11
