y is function of x
for x=0.1, y=14.2
for x=0.2, y=15.04
How do I find x for y=15.75?
Do I have to keep plugging x into function till I get y I need or is there a faster way?

Bump! Help me out here please. Y is a bunch of long equations and I dont want to solve them for every x. Is there a way to approximate x?

No x can not be approximated, the only thing you can do is try every number until you find the answer

How the fuck are we supposed to answer this if you don't tell us what the function is?

Find x=f^-1(y) and plug in 15.75

You can attempt to solve it numerically, but with no indication of discontinuities and asymptotes there's no guarantee that a small change in x when y is near your magic number will be helpful, nor any guarantees to increase or decrease x to get closer to y
