Answer:

f(x) = -2 (x + 2)² - 4

Step-by-step explanation:

f(x) = a (x - h)² + k (h , k) is vertex h = -2 k = -4

pass point (-1 , -6) f(x) = -6 and x = -1

-6 = a (-1 - (-2))² + (-4)

-6 = a - 4

a = -2

quadratic function: f(x) = -2 (x + 2)² - 4

Can anyone help me with this math problem?

Lemme give you a cheap answer, by simply using the "compound interest formula", which is what that is, 2% compounded yearly

thus $\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad 
\begin{cases}
A=\textit{current amount}\to&\boxed{y}\\
P=\textit{original amount deposited}\to &\$23000\\
r=rate\to 2\%\to \frac{2}{100}\to &0.02\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{per year, meaning once}
\end{array}\to &1\\

t=years\to &\boxed{x}
\end{cases}$

plug in those values, and simplify
