Answer 1

\[y = 3x{^3} - 5x{^2} + 3x - 4\]\[y' = 9x{^2} - 10x + 3\]\[y'' = 18x - 10\]\[y'''=18\]\[y''''=0\]

Answer 2

What is your reasoning?

Answer 3

I thought polynomials are always infinitely differentiable?

Answer 4

oh i went into flow only 3. so sorry my example will go upto to fifth differential
