Would this be a concert you would want to take your little sister to? is this a concert geared towards kids?

This wouldn't be a good concert to take your little sister to (or for any kids in general) since the median (2nd quartile) age of the audience is 33. Also, it mainly ranges from 15 to 40 (since 15 is the first quartile and 40 is the third quartile). This means the concert is mainly for teens to adults.

No, because most of the people were from 15 -40 years old and it’s  not geared towards kids.

step-by-step explanation:

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
