x2 - X 4 Let f be a function such that x2 sf ( x) s- _x' + 1 for all -2 s x s 2. What is lim f(x)? x -0 O The limit is 0. The limit is 1. O The limit does not exist. O The limit cannot be found because f(x) is unknown.The equation of the normal line of the function f(x) = Vx +2 at x = -1 is O y= -2x - 1. O y= -2x + 1. O y=. X - N / W 2 O Y= X+ N / WA graphing calculator can be used on this question. Which type of discontinuity exists at x = 0 for the function f(x) = cos X O jump O infinite O oscillating O removable
