Find the inverse of f(x) if f(x) equals (3X + 7)/(X-2)
THanks So much!
In mathematics, an inverse function is a function that undoes another function: If an input x into the function ƒ produces an output y, then putting y into the inverse function g produces the output x, and vice versa. i.e., ƒ(x)=y, and g(y)=x
Now I'll try to solve for "x ="
y=(3x+7)/(x-2)
y(x-2)=3x+7
yx-2y=3x+7
yx-3x-2y=7
x(y-3)-2y=7
x(y-3)=7+2y Divide with (y-3)
x=(7+2y)/(y-3)
Inverse fonction of:
y=(3x+7)/(x-2)
x=(2y+7)/(y-3)
