FunctionFind the inverse function of g(x)=-2/(x+1)
1 Answer | add yours
We'll determine the inverse of g(x) in this way.
Let g(x) = y
y = -2/(x+1)
Now, we'll find x with respect to y. F
y(x+1) = -2
We'll remove the brackets and we'll get:
yx + y = -2
We'll isolate x to the left side and we'll get:
yx = -2 - y
We'll divide by y:
x = -(2+y)/y
Therefore, the inverse function is: f^-1(x) = -(2+x)/x
