Let f be the function defined above . Which of the following statements is true ?

f(x)={ x2 -20 for x<5

{-x2 +20 for x≥5


Let f be the function defined above . Which of the following statements is true ?



A) f is not differentiable at x = 5 because f is not continuous at x = 5

B) f is not differentiable at x = 5 because the graph of f has a sharp corner at x = 5

C) f is not differentiable at x = 5 because the graph of f has a vertical tangent at x = 5 .

D) f is not differentiable at x = 5 because f is not defined at x=5
