1.已知函数f(x)是定义在R上的偶函数,且f (2﹣x)=f(x)当x∈[0,1]时,f (x)=e﹣x,若函数y=[f (x)]2+(m+l)f(x)+n在区间[﹣k,k](k>0)内有奇数个零点,则m+n=( )
2.秦九韶是我国古代数学家的杰出代表之一,他的《数学九章》概括了宋元时期中国传统数学的主要成就.由他提出的一种多项式简化算法称为秦九韶算法:它是一种将n次多项式的求值问题转化为n个一次式的算法.即使在现代,利用计算机解决多项式的求值问题时,秦九韶算法依然是最优的算法.用秦九韶算法求多项式f(x)=4x5﹣x2+2,当x=3时的值时,需要进行的乘法运算和加法运算的次数分别为( )
