Let Us Do Activity 2. What's My Tangent Line? Direction: Determine point-slope form equation of the tangent line to the following: (show your complete solution) 1. f(x) = Vx- 1atx = 1 2. f(x) = V3x - 1 at x = 3. f(x) = 1 - 2x at P(1, -1) Let Us Apply Activity 3. Let's Make a Short Cut! Direction: Find the point-slope form equation of the tangent line. (Show complete solution) A tour guide is planning to make a new trail in Sanchez Peak through point A, perfectly tangent to the old trail as shown on the mini map below. Find the equation of the tangent line in point-slope form if the equation of the old trail is f (x) = x2 - 3x + 1 and point A is in coordinate (1, -1)
