Use Function Notation to write a formula for the function whose graph is shown below.

$\displaystyle {f{{\left({x}\right)}}}={\left\lbrace\begin{array}{cc} -{0.75}{x}-{3}&{x}<{4}\\-{0.75}&{4}<{x}\le{8}\end{array}\right.}$
$\displaystyle {f{{\left({x}\right)}}}={\left\lbrace\begin{array}{cc} -{0.75}{x}-{3}&{x}<{4}\\{0}&{4}<{x}\le{8}\end{array}\right.}$
