The answer is: [B]: -4 .
_____________________________
Here is the problem:
_____________________
"Find f(3)."
_______________________
f(x) =
\left \{ {x + 5 ; if x \ \textless \ -2 ; \atop {-4; if x \geq -2 ;}} \right. ;
______________________________________
Since we are asked to find: " f(3)" ; we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is, " 3
\geq -2" ;
and f(x) = -4 if x
\geq -2 .
_____________________________________________________
So, in this case, f(x) = f(3) = -4 ; which is: "Answer choice: [B] ".
