In this question we re-define the operations addition and multiplication as follows: a+b is defined as the minimum of a and b, while a∗b is defined to be the sum of a and b. For example, 3+4=3, 3∗4=7, and 3∗42+5∗4+7=min(3 plus 4 plus 4,5 plus 4,7)=min(11,9,7)=7.
Let a,b,c be real numbers. Characterize, in terms of a,b,c, what the graph of y=ax2+bx+c looks like.
