Question

If f(x) = 2x+1/x-4 what is the value of f^-1(3)

Answer 1

Answer:

f^-1(3) = 1.719 or  f^-1(3) = 0.149

Step-by-step explanation:

for inverse function x and y coordinates are flipping so graph the function and find for what x - coordinate y- coordinate = 3

in case that f(x) = $2x + \frac{1}{x-4}$ than f^-1(3) = 1.719

in case that f(x) = $2x + \frac{1}{x} -4$ than f^-1(3) = 0.149
