Using quadratic function concepts, it is found that Abby made a mistake on the coordinates of the vertex, which are (-4,1).
----------------------
- A quadratic function is defined by:
- The y-intercept is given by point:
- The vertex is given by:
. - The axis of symmetry is:
----------------------
The function given is:
- Which is a quadratic equation with:
. 
, thus, the y-intercept is (0, -15).
- Thus, the <u>x-coordinate of the vertex</u> is x = -4, which is the same as the <u>axis of symmetry</u>.
- The vertex is given by: (-4,1).

Answer:
$600,000 is your answer.
Step-by-step explanation:
What you do is multiply.
$375,000 x 12% x 5 = 225,000
$375,000 + 225,000 = $600,000 is your answer.
The house is now worth $600,000
Okay. Let’s begin!
I order to solve this problem we must u do it and redo it. We have to find the diameter and the radius
Step one: 15 divided by 3.14 (PI) which is 4.77707006. That’s the diameter. Now divide that by two for the radius which is 2.38853503
Step two: find the area
Formula: PI(r)^2
Step three: solve for the area
3.14(2.38853503)^2
Step four: answer
Your answer is.....
17.9140127. Or if ur rounding:
18.
I hope this helped!
