Let f(x) = |x - 7. a) Find lim -0-4 b) Find lim h0+ f(7+h)-f(7) h f(7+h)-f(7) h c) Mark all statements that are true about f (there might be more than one answer that is correct). f(7+h)-f(7) h A. f(x) is not differentiable at a = 7 because lim B. f(x) is not continuous at a = = 7. c. f(x) is differentiable at a = 7. -0-4 D. f(x) is not differentiable at a = 7 because lim h0 f(7+h)-f(7) h lim h0+ f(7+h)-f(7) h does not exist.
