Let f be the function defined as f(x)= 2 for x<4 f(x)= 4x-3 for x≥4 Which of the following statements is true? f is not differentiable at x = 4 because fis not defined at x = 4. f is not differentiable at x = 4 because the graph of f has a cusp at x = 4. f is not differentiable at x = 4 because the graph of f has a vertical tangent at x = 4. f is not differentiable at x = 4 because f is not continuous at x = 4,
