proof of convexity 3

proof of convexity 3

i hav a function of 7 variables, suppose i plot the function while varying
any one variable at a time, the function is visually convex, can i
conclude that the function is convex for all possible
x1,x2,x3,x4,x5,x6,x7.. (note i have also plotted the function varying any
two variables, and all (7 choose 2) plots are visually convex (bowl
shaped).. also, can u possibly point me towards some reference text. that
may help me out, thanks alot..
