What are the dimensions of the rectangle shown below? remember to use the axes on the coordinate grid to you. a coordinate grid is shown with scale from negative 14 to 0 to positive 14 on both x- and y-axes at increments of 2. a figure abcd is shown with a at ordered pair negative 10, 2, b at ordered pair 2, 2, c at ordered pair 2, negative 6, and d at ordered pair negative 10, negative 6.

he is often referred to as a man of twists and turns

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
