Answer:
6x
Step-by-step explanation:
3x*3x= 9x - 3x = 6x
Answer:
it's a rectangle so the area is 6×8=48
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
