Answer:
The vertex is the point (-1,2)
Step-by-step explanation:
we have
![f(x)=x^{2}+2x+3](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E%7B2%7D%2B2x%2B3)
Convert into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
![f(x)-3=x^{2}+2x](https://tex.z-dn.net/?f=f%28x%29-3%3Dx%5E%7B2%7D%2B2x)
Complete the square. Remember to balance the equation by adding the same constants to each side.
![f(x)-3+1=x^{2}+2x+1](https://tex.z-dn.net/?f=f%28x%29-3%2B1%3Dx%5E%7B2%7D%2B2x%2B1)
![f(x)-2=x^{2}+2x+1](https://tex.z-dn.net/?f=f%28x%29-2%3Dx%5E%7B2%7D%2B2x%2B1)
Rewrite as perfect squares
![f(x)-2=(x+1)^{2}](https://tex.z-dn.net/?f=f%28x%29-2%3D%28x%2B1%29%5E%7B2%7D)
----> equation in vertex form
The vertex is the point (-1,2)
Answer:
i really wish i could help but i have no idea );
Step-by-step explanation:
$-447.82
If she is widthdrawling and paying with money that she doesn’t have, before she puts her paycheck in, then she is in debt of $447.82 which makes it negative.
