Multiple Choice

Give a rule for the piecewise-defined function. Then give the domain and range.
-

A) $\text { } f(x) =\left\{\begin{array}{ll}-6 & \text { if } x \leq-2 \\-1 & \text { if } x>-2\end{array} ; \text { Domain: }(\infty, \infty) \text {, Range: }\{-6,-1\}\right.$
B) $f ( x ) = \left\{ \begin{array} { l l } - 6 & \text { if } x < - 2 \\ - 1 & \text { if } x \geq - 2 \end{array} ; \right.$ Domain: $\{ - 6 , - 1 \}$ , Range: $( x , \infty )$
C) $f ( x ) = \left\{ \begin{array} { l l } - 6 & \text { if } x \leq - 2 \\ - 1 & \text { if } x > - 2 \end{array} ; \right.$ Domain: $\{ - 6 , - 1 \}$ , Range: $( \infty , \infty )$
D) $f ( x ) = \left\{ \begin{array} { l l } - 6 & \text { if } x < - 2 \\ - 1 & \text { if } x \geq - 2 \end{array} ; \right.$ Domain: $( \infty , \infty )$ , Range: $\{ - 6 , - 1 \}$
