For this case we have the following system of equations: Rewriting the equations we have: Then, we write a table for each function in the following interval: [-4, 4]. We have then: To : -4 -3 -3 -1.666666667 -2 -0.333333333 -1 1 0 2.333333333 1 3.666666667 2 5 3 6.333333333 4 7.666666667 To : -4 -3 -3 -4 -2 -5 -1 -6 0 -7 1 -8 2 -9 3 -10 4 -11 Therefore, the ordered pair solution is the one that has the same value in both tables. We have then: (-4 , -3) Answer: The solution is: A. (-4,-3)
