1) When finding a median, order your numerical list from smallest to larger, as so: 2,2,3,4,5,6,8,9. 2) Then start eliminating numbers from each side of the order; (The bolded numbers will be removed.) 2,2,3,4,5,6,8,9 2,3,4,5,6,8,9 2,3,4,5,6,8 3,4,5,6,8 3,4,5,6 4,5,6 4,5 3) Since there is an even number of digits in your list, you will have to add the last two digits and then divide them by two. 4 and 5 are the last numbers standing, (4+5=9)(9/2=4.5) and therefore your answer, would be 4.5, or B.
The discriminant can be determined from the number of roots of the graph.
If Disc> 0, the function has two distinct roots If Disc = 0, the function has a repeated root If Disc < 0, the function has no real root.
Since the given graph has no real root, i.e. it does not cross x-axis at any point, so we can say that the discriminant of the given function is negative.
It is a reflection because it’s mirrored across the y-axis, like looking at the side of your face in the mirror. A translation is the same thing and moving it from one set of coords to another, without turning it. A rotation would be turning it, which A’B’C’D’ is neither of.
