Find two straight lines that are perpendicular to y=0.25x and tangent to the curve f(x) = 1/x.
f(x) = 1/x.
The Attempt at a Solution
What I did was equate y and f(x) and determined when they equal which is 2 and -2. The points are (2, 1/2) and (-2,-1/2).
Now, I took the derivative of f(x) and got -1/x^2. Would I use this to find the slope at the two points? Then I could make the equation.
