The function
... f(x) = (x+2)/(x-1) = 1 + 3/(x-1)
is symmetrical about the line y=x, hence is its own inverse.
We can evaluate the desired derivative directly.
... f'(x) -3/(x-1)²
so f'(2) is
... f'(2) = -3/(2-1)²
Answer:
2x + y = 4
4x + 2y = 12
Step-by-step explanation:
Equations 2x + y = 4 & 4x + 2y = 12 haven't the same solution.
