Question

How do you get R= S/0.75 from S= R-0.25R
(inverse function)

Answer 1

R-0.25R=0.75R

S=0.75R --> R=S/0.75 dividing both sides by 0.75.

Answer 2

no the original equation was S=R-0.25R.
I want the inverse function and i wanna know how

Answer 3

The inverse function is the function that reverses the mapping.

so if you have a function S=R-0.25R that's the same as S=0.75R, which is a straight line.
For every value of R it will produce a value of S.

The inverse function is one where you have every value of S produce a value for R.

So in this case, all you need to do, is rearrange the equation to get R= something to do with S.

Answer 4

Okay I got it now. Thanks
