Find the equation, (f(x) = a(x-h)2+ k), for a parabola containing point (-1,0) and having (-3, 4) as a vertex. What is the stand

$\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\
-------------------------------\\\\
vertex~(-3,4)\quad 
\begin{cases}
x=-3\\
y=4
\end{cases}\implies \stackrel{f(x)}{y}=a[x-(-3)]^2+4
\\\\\\
y=a(x+3)^2+4
\\\\\\
\textit{we also know that }(-1,0)\quad 
\begin{cases}
x=-1\\
y=0
\end{cases}\implies 0=a(-1+3)^2+4
\\\\\\
-4=4a\implies -1=a\qquad therefore\qquad y=-(x+3)^2+4$

What are two numbers that multiply to the value on top and add to the value on bottom

HACTEHA [7]

is this correct?

a * b = -70

a + b = -9......a = -9 - b

b(-9 - b) = -70

-b^2 - 9b + 70 = 0

(-b + 5)(b + 14) = 0

-b + 5 = 0

5 = b

b + 14 = 0

b = -14

ur numbers are -14 and 5

-14 * 5 = -70

-14 + 5 = -9
