Function that best describe the graph: Based on the graph there are four zeros of the polynomial function which are the values of {eq}x {/eq} that intersecting the x-axis, two of them are negative and two are positive.Thus what we are going to do is find...
Which is a possible equation for the provided graph? ( ) A. f(x)= (3(x^2-x-6))(x^2-5x-6) B. f(x)= (x^2-x-6)(x^2-5x-6) C. f(x)= (x^2-x-6)(x^2-5x-6) D. f(x)= ((x+3)(x-2))((x+5)(x-1)) 相关知识点: 试题来源: 解析 B 反馈 收藏 ...
Which of the following describes the graph of the equation (x+y)2=x2+y2?A.the empty setB.one pointC.two linesD.a circleE.the entire plane 答案 CExpanding the left side, we have x2+2xy+y2=x2+y2⇒2xy=0⇒xy=0⇒x=0 or y=0.Thus there are two lines described in this gr...
