1 Select the correct answer.
If x is a number that is 7 more than y, how do you express x as a function of y?
O A.
X = fy) = 7 + x
OB. X = f(y) = 7 + y
OC. y = f(x) = 7x
OD. y= f(x) = y - 7
O E. y = f(x) = 7 + y

O A.

X = fy) = 7 + x

OB. X = f(y) = 7 + y

OC. y = f(x) = 7x

OD.y= f(x) = y - 7

O E. y = f(x) = 7 + y

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
