Work Step by Step

$f(x)= ax^{2}+b\mathrm{x}+c \quad $or $\quad f(x)=a(x-h)^{2}+k$ A quadratic function is defined for all real numbers, domain$:\quad \mathbb{R}=(-\infty,\infty)$ The graph of f(x) is a parabola. If the parabola opens down, the vertex is its maximum point. At $x=-3$ the maximum of $f(x)$ is $-4.$ The range of f is $(-\infty,-4] $
