MIND   BUSTER

Sec. 4.5 ­ Interpret Graphs of Quadratic Relations

1.   Answer the following about the graph to the right:a)  Coordinates of the x­intercepts

b)  Coordinates of the y­intercept

c)  Axis of Symmetry

d)  Min/Max point

e)  Vertex

2.   Find the y­intercept for the following: a)  y = 2x2 + 4x + 8 b)  y = 2(x ­ 7)2 + 6

3.   The equation representing your jump off a skateboard ramp isrepresented by h = ­0.8t2 + 2 where t represents time in seconds and h represents your height above the ground in metres.a) Use transformations with a, h, and k to make a sketch of this graph.b) How high off the ground is the ramp that you jumped off of?c) How high will you be after 1 second?d) How long will you be in the air?
