1.A function has exactly 3 zeros; they are -1,0,and 2.The function passes through the point (1,6).Sketch the function,find the equation for function.
2.Find the asymptotes of the following functions.if it does not have a particular type of asymptotes(verticle,horizontal,or oblique) then briefly say why it does not.describe the end of behaviour of each function.find the intercept.draw the graph.remeber to plot a decent number of points on either side of any intercepts so your curves look reasonable.draw and label the asymptotes
a)q(x)=5x-1/x^2-2x-3
b)s(x)=3x-2/x-1
第二題看不懂的話(huà)把第一題解了就好啦,如果能解第二題更好!

優(yōu)質(zhì)解答

1)f(x)=a(x+1)x(x-2)將（1,6）帶入,得a=-3f(x)=-3x(x+1)(x-2)圖沒(méi)法傳,知道x正無(wú)窮時(shí)是負(fù)的,就出來(lái)了第二問(wèn)再說(shuō)2）分母為0時(shí)的x值肯定是漸近線,趨向無(wú)窮第一個(gè)的x=-1和x=3第二個(gè)的x=0 還有x趨向無(wú)窮時(shí),分母為0,此時(shí)...
