Answer:
y = 1/2x +7
Step-by-step explanation:
I like to start with the 2-point equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) + y1
y = (9 -8)/(4 -2)(x -2) +8 . . . . . fill in point values
y = 1/2(x -2) +8 . . . . . simplify a bit
y = 1/2x +7
Let g the inverse function of f.
The most important property of g and f being inverses of each other, is that
g(f(x))=x, also f(g(x))=x
so, what one function 'does' to x, the other 'undoes' it.
Thus, we have:
f(g(x))=x and alos f(g(x))= -g(x)+3, from the rule
thus :
-g(x)+3=x
-g(x)=x-3
g(x)=-x+3
check: f(g(x))=f(-x+3)=-(-x+3)+3=x-3+3=x
Answer: the inverse of f is g, such that g(x)=-x+3
3 of anything positive is greater than 2 of the same thing.
I can't think of an exception.

Hi there!
There is an initial cost of $210,000 (which you're just going to pay once)
Then it costs $500 per day to operate.
The number of days is represented by "x".
Your equation in function notation should look like this :
f(x) = 500x + 210,000
There you go! I really hope this helped, if there's anything just let me know! :)
