need help with these three questions

2. Provide an example of a quadratic function of the form y = ax2 + bx + c so that a tangent line exists a horizontal tangent exists at x = 2. Explain/ show your work why your function works 3. What error was made when attempting to take the derivative of y = (at2 + 2x 3)3. Provide the correct derivative. y' = 3(2x + 2)2 Page | 1 4. Is it possible to find the equation of a tangent line to the function y = (x 3)2 2 at the point (3,0)? Explain
