Choose all the statements below that are TRUE. If a function is differentiable at a point x, then it must be continuous there. If a function is continuous at a point as, then it must be differentiable there. If a function is not continuous at a point so. then it is denitely not differentiable there. If a function is not differentiable at a point 9:, then it is definitely not continuous there. If a continuous function has a vertical tangent line at a point :6 in its domain, then it is not differentiable at that point. DECIDE] D By denition, if humm f'(a:) exists, then f! is differentiable at a and the limit is f'(a)
