Over which interval is the graph of f(x)=1/2x2+5x+6 increasing?

489

Step-by-step explanation:

6×9+6+9+210÷2=105×4=420

because 1.2 isnt half of 6 duh

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
