You can put this solution on YOUR website!
find the inverse of Y=4x and y=x-2
in these equations called functions , x is considered independent variable and y as dependent variable. generally you find Y on the l.h.s. expressed explicitly as equal to some function of x ....as 4x in the above example
to find inverse means we have to express x as function of y
hence we have y = 4x
x = y/4 ...is the inverse
for the second example y = x - 2
x = y+2 ...is the inverse
