The volleyball team and the wrestling team at newton high school are having a joint car wash today,
and they are splitting the revenues. the volleyball team gets $1 per car. in addition, they have
already brought in $50 from past fundraisers. the wrestling team has raised $10 in the past, and
they are making $5 per car today. after washing a certain number of cars together, each team will
have raised the same amount in total. how many cars will that take?

range is infinite on both x and y axis positive and negative

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
