Explanation:
The concavity of a function is the sign of its second derivative.
If, in a set, it is positive, than the concavity is up, if negative the concavity is down, if it is zero, there could be an inflection point there.
Thus, y=2x+3
y2
Since the second derivative is always negative, it has always concavity dawn.
