So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
Answer:
6 and -12
Step-by-step explanation:
6×-12=-72
6+(-12)=-6
×^2 -6x-72=0
(x+6) (x-12)
x^2-6x-72=(x+6) (X-12)
So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
