The first derivative gives the [ ] of yyy with respect to xxx.
A
The sign of f′′(x)f''(x)f′′(x) must change across x=ax=ax=a.
B
The gradient may be negative but becoming less negative.
C
If f′′(x)>0f''(x)>0f′′(x)>0, the gradient is increasing as xxx increases.
D
The first derivative gives the instantaneous rate of change of yyy with respect to xxx.
