What is the equation for this graph in standard form

The vertex is at (-3,-2) on the graph; the vertex equation is (x- -3)^2 +-2 =y; (x+3)^2 -2=y; now put this in standard form x^2 +9+6x-2=y; x^2 +6x+7=y

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
