(a) Use the quadratic formula to determine, to the nearest tenth, the roots of the
equation:
x2 + 2x – 2 = 0.
(b) Determine the vertex of the parabola y = x2 + 2x – 2. (recall the x value of the vertex
is given by x = -b/2a)
(c) Use parts a and b to sketch the graph of y = x2 + 2x- 2.

Assume you are standing on Venus. How high will a baseball that is thrown up into the air at 48 feet per second go if it starts its flight at a height 8 feet above the ground? (Hint this is another application of the quadratic, recall the x value of the vertex is given by x =
-b/2a)
