45、2f xxx的对称轴为1x，则函数()f x的单调区间为(,1),1,)，且函数()f x在(,1)上为减函数，在1,)上为增函数，函数()g x的单调区间为2,4，且函数()g x在2,4上为增函数；（2）当1x时，min()1f x，因为函数()g x在2,4上为增函数，所以2min()(2)22 20g xg2解：由矩形的宽为x m，得矩形的长为3032xm，设矩形的面积为S，则23033(10)22xxxSx，当5x时，2max37.5Sm，即宽5xm才能使建造的每间熊猫居室面积最大，且每间熊猫居室的最大面积是237.5m3判断()f x在(,0)上是增函数，证明如下：设120 xx，

46、则120 xx，因为函数()f x在(0,)上是减函数，得12()()fxfx，又因为函数()f x是偶函数，得12()()f xf x，文档编码:CS9I7N1F6M8 HL6Z1L10S5W1 ZZ5J8H8G1C2文档编码:CS9I7N1F6M8 HL6Z1L10S5W1 ZZ5J8H8G1C2文档编码:CS9I7N1F6M8 HL6Z1L10S5W1 ZZ5J8H8G1C2文档编码:CS9I7N1F6M8 HL6Z1L10S5W1 ZZ5J8H8G1C2文档编码:CS9I7N1F6M8 HL6Z1L10S5W1 ZZ5J8H8G1C2文档编码:CS9I7N1F6M8 HL6Z1L10S
