Solve for y: f(-5)=13+2x
I assume you mean: f(x) = 2x - 1 There is really nothing to "solve" here. This is the description of a function. For a specific value of "x", you can replace that value, to find out the value of the function. This is basically the same as evaluating: y = 2x - 1
y = f(x) = (2x + 1)/(x - 1)y*(x - 1) = (2x + 1) xy - y = 2x + 1xy - 2x = y + 1x(y - 2) = y + 1so x = (y + 1)/(y - 2) assuming y�2.So the inverse function is f-1(x) = (x + 1)/(x - 2)

X = 0 (zero) Y = -1 (neg 1)
