Answer:

f^-1 (x) = 2X + 8

Step-by-step explanation:

Let's make f(x) = y

Y = X/2 - 4

So to find the inverse, switch the y with the x like so:

X = Y/2 - 4 (isolate the Y value)

X + 4 = Y/2 (multiply both sides by 2)

2(X + 4) = Y

Y = 2X + 8

So f^-1 (x) = 2X + 8

Can someone help please?
Alekssandra [29.7K]

Answer:

y=1X

Step-by-step explanation:

This is because the distance over the money made over the days worked is 2/2 which simplifies to 1 so that would be the one x. then the y intercept is found on the y axis where does the line cross the y axis? this would be at zero so you do not need to put that in the equation
