要懂英文和数学的.
(1)Find asymptotes of g(x) if f(x) has asymptotes of x = 11 and y = -7 where f(x) = 2g(x - 7) - 3
(2)Find and give the zeros and their multiplicities (in the same order as the zeros,of the following function f(x) = x^3+ x^2 - x - 1
希望高手能帮手!
我不是要翻译啊,好像好多人都误会了。
修改啦,之前负号没瞧见:
第一题:f(x) = 2g(x - 7) - 3的渐进线是x=11,y= - 7.g(x)=(f(x+7)+3)/2的渐进线自然就是 x+7=11 和y=(-7+3)/2即x=4,y= - 2.理由你要去看渐进线的极限定义.
第二题:x^3+x^2-x-1=(x+1)(x^2-1)=(x+1)^2(x-1)所以zeros are:-1 and 1,multiplicity for -1 is 2 and the multiplicity for 1 is 1.很简单,multiplicity就是因式分解后的那个根对应的指数
