The Answer of Let $f ( x ) = \frac { 2 x ^ { 2 } + 3 x + 6 } { x + 2 }$ . Use the graphs of f and $f ^ { \prime }$ to estimate, to two decimal places,
(a) the interval(s) where f is decreasing.(b) the interval(s) where f is concave upward.(c) the critical numbers of f .

Let f(x)=2x2+3x+6x+2f ( x ) = \frac { 2 x ^ { 2 } + 3 x + 6 } { x + 2 }f(x)=x+22x2+3x+6​

Let $f ( x ) = \frac { 2 x ^ { 2 } + 3 x + 6 } { x + 2 }$
