A machine makes 640 fl oz of yogurt. Each serving is 8 fl oz. The amount of yogurt left after x servings
is described by the function f(x) = 640 -&x. What
is the value and meaning of each intercept?

Find the directions in which the function increases and decreases most rapidly at upper p 0p0. then find the derivatives of the function in these directions. f(x,y)equals=x squared plus xy plus y squaredx2+xy+y2, upper p 0p0left parenthesis 1 comma negative 4 right parenthesis
