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