Question

Evaluate the function for the given values of x.
-$f ( x ) = \left\{ \begin{array} { l l } - 5 x + 4 , & \text { for } x < - 1 \ x ^ { 2 } + 3 , & \text { for } - 1 \leq x < 2 \ 1 , & \text { for } x \geq 2 \end{array} \right.$
(a) $f ( - 1 )$; (b) $f ( 3 )$
A) (a) 9; (b) 12
B) (a) 4 ;
(b) 12
C) (a) $4 ;$ (b) 1
D) (a) $9 ;$ (b) 1

Quizplus · Accepted Answer

For (a) $f(-1) = (-1)^2 + 3 = 1 + 3 = 4$, because $-1$ falls in the range $-1 \leq x < 2$. For (b) $f(3) = 1$, because $3$ falls in the range $x \geq 2$.
