-axis at Q. Find the equation of the curve if the area of triangle OPQ is 6 square units.

To find the equation of the curve, we need to determine the function f(x).

Let's consider a point P(x, y) on the curve. The slope of the tangent line at P can be represented as dy/dx.

Since the tangent line passes through (1, 1), we can write the equation of the tangent line as:

y - 1 = dy/dx(x - 1)

Since the tangent line cuts the x-axis at Q, the y-coordinate of Q is 0. Plugging this into the equation of the tangent line, we get:

0 - 1 = dy/dx(x - 1)
-1 = dy/dx(x - 1)
dy/dx = -1/(x - 1)

Now, let's find the equation of the curve by integrating dy/dx with respect to x.

∫dy/dx dx = ∫(-1/(x - 1))dx
∫dy = -∫(1/(x - 1))dx
y = -ln|x - 1| + C

To find the constant C, we can use the fact that the curve passes through (1, 1). Plugging these values into the equation, we get:

1 = -ln|1 - 1| + C
1 = C

Therefore, the equation of the curve is:

y = -ln|x - 1| + 1
