Consider the quadratic function in standard form:y=−3x2+ 6x+ 9.(a) Use the quadratic formula to write the function in factored form.(b) Find thex-intercepts of the graph of the function, if they exist.(c) Find they-intercept of the graph of the function.(d) Write the function in vertex form by Completing the Square, and find the vertex.(e) Is the vertex a maximum or a minimum? Justify your answer mathematically.(f) Sketch a graph of the function, showing all important features. Your graph does not needto be to scale   please help me answer all parts since it a sequence question
