The equation x=-3 is:

C

Step-by-step explanation:

It Is not a function, please check out the definition of function on google.

Since x=-3, as a vertical line, has infinite values of y associated with this single value of x this is not a function. hope this helps.

Step-by-step explanation:

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

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
