John and Wesley both work for telephone companies installing internet connections into new homes, but they do
not work for the same company.
John's paycheck at the end of the month includes his base
pay of $2,000 and his commission of $65.25 for each
installation he makes that month. Wesley is paid $380 plus
a commission of $105.75 for each installation he makes
each month.
In September of last year, they both made the same
number of installations and they both earned the same
amount of money.

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

the answer will be b x² +x-1
