Which function is graphed below? f(x) = -cos(x)
f(x) = cos(x)
f(x) = sin(x)
f(x) = -sin(x)

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
