Hi! I need assistance with these. Thank you!

Using the limit definition of the derivative of the tangent line to the function f (given below), which of the following is INCORRECT? * f (x) = 2x+9 Of' (x) = limp- 2r+24+9-2r-9 h Of' (x) = limp- [2(x+h)+9]-2r+9 h Of' (x) = limp-to [2(x+h)+9)-(2r+9) 2 Which of the following is a function continuous at the specified value of "a" but not differentiable at "a"? Of (x) = x2 - 2x ; a = 1 Of ( x) = 1x] ; a =0 Of (x) = 1; a=3 Of ( x) = 3; a=0 3 The function f(x) is NOT differentiable at the following interval EXCEPT f (x) = V3 - 2x O (1, 5) O (-oo, 1.5] O (-3, 2) O [-1, 4] 4 What is the equation of the tangent line to the graph of the function (given below) at x=-2? * 8 (x) = 3x2 - 2 Oy = -12x - 34 O y = -12x - 14 O y = -12x + 34
