1: You want to find the equation for an unknown S" degree function. You will need a system of______ equations with a minimum of 6- equations. 2: The equation of the function y= x3 after ti has been reflected in the y-axis, compressed horizontally by a factor of 1/3 and vertically shifted down 5 would be 3: Astudent needs a function to model the graph which passesthrough the points listed the stole. here: (0,11) (2,5) (-3,50) (8,83) (5,6). After much work the student comes up withthe cubic function: y = x-3 +3x2 - 5x +1 a) Explain why you can not use finite differences to verify that thesepoints do form a cubic function b) Is the student's equation correct? Why or why not
