Question

What is the equation of the tangent line of `f(x) = (4x)/(x-1)` at `x=0`?

Answer 1

Equation of tangent i.e `dy/dx = f'(x) = -4` at `x=0`

Explanation:

Alright so whenever equation of tangent is required it basically means the derivative of the function, since a point is given it means tangent/derivative at that particular point on the given curve. By using the quotient rule, derivative is taken and put `x = 0` for the required answer.

Hope that helps,
Cheers.
