Find f (-4) if f(x) = 3x - 10

  -22

Step-by-step explanation:

Put -4 where x is and do the arithmetic.

  f(-4) = 3(-4) -10 = -12 -10

  f(-4) = -22

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
