1 --- What is the axis of symmetry of the graph of y = 2(x – 3)2 – 7?
2 --- What are the x– and y–intercepts of the graph of y = 2x2 + 6x + 4?

2) by using the quadratic formula you get x intercepts are -4+(sqrt(41))/2 and -4 -(sqrt(41))/2 and you get y intercept of 4
#1) by taking the first derivative of the equation y=2x^2-12x +11 (which is your equation) you get
y= 4x-12 and x=3 thus the axis of symmetry is x=3
