Y=f(x)=-3x find f(x) when x=3

need

f(3) = - 9

Step-by-step explanation:

to evaluate substitute x = 3 into f(x)

f(3) = - 3 × 3 = - 9

109 is the nearest whole number/final answer! : )

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
