F(x)=2x-33 need explaining this to somebody

Ok so it looks like you have to solve for function of x. That what f(x) means. To do that you can graph it. The x - intercept is (16.5, 0) , and the y-intercept is (0, -33)

(4,5

look up a corrdinate plane and do what the thingy says and boom

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
