Remark
Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.
Solution.
The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.
When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.
When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.
So the answer is C <<<<< Answer.
When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.
Answer:18
Step-by-step explanation:
3x6
6+6+6
12+6
18
3x6=18
Substitute each value until the answer is correct
a. 1 = -4 x -5 -1
1 does not equal 19
b. 15 = -4 x 4 -1
15 does not equal -17
c. -5 = -4 x 1 -1
-5 equals -5
just to make sure the last answer is incorrect
d. -7 = -4 x 2 -1
-7 does not equal -9
