A parabola that has a negative slope but is curving down...
Indicates speeding up because the slopes of the tangent lines at each point are getting more negative and increasing in magnitude

A parabola that has a negative slope but is curving up...
Indicates slowing down because the slope of the tangent lines at each point are getting less negative thus, decreasing in magnitude.
