HURRY HEL PL Which data set is represented by the modified box plot?

Box and whisker plot on a number line from 40 to 120 in increments of 5. The whisker ranges from 66 to 85. The box ranges from 68 to 82 with the vertical bar inside the box at 75. One dot mark above forty-six. One dot mark above one hundred and eight.

85, 70, 80, 108, 46, 66, 68, 82, 70, 68

85, 78, 80, 108, 46, 66, 68, 82, 72, 80

85, 78, 80, 108, 46, 66, 68, 82, 72, 68

85, 78, 80, 108, 46, 66, 68, 80, 72, 68

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
