Hello, I need help finding the intersection points B and C of the tangent A with for horizontal axis B and the vertical axis C.
hyperbola: f (x) = 1 / x
A = (1, 1)
Thanks for your help .

f' = 1/x^2
at (1,1) y' = 1
so, you have a point and a slope.
y1 = 1(x1)
you can probably find the intercepts from here, no?

B = (2, 0) and C = (0, 2) but we have explained how to find this result.
