It means you should rearrange the equation so that x is on one side of the equal sign, and everything else on the other, with no "x" on the right side of the equation.
For instance, if I was told to express x as a function of y and given the equation:
x-4y=6
I would express x as a function of y by rearranging the equation to read:
x = 6+4y

y and x are a example,like so: The mother board is the function of a computer the mother board is the Y and A computer is the x you replace y and x with something else its like filling the blanks what does _____ have to do with _____= what does Y have to do with X= what does time have to do with space
The inverse of the function y = x is denoted as y = x. The inverse function essentially swaps the roles of x and y, so the inverse of y = x is x = y. In other words, the inverse function of y = x is the function x = y.
y = x This is a line and a function. Function values are y values.
A binary function is a function f if there exists sets X, Y, and Z, such that f:X x Y -> Z where X x Y is the cartesian product of X and Y.
implicit function/? an equation the function(x,y)=0 defines y implicitly as a function of x the domain of that implicitiy defines function consists of those x for which there is a unique y such that the function (x,y)=0
