Sketch the graph of the function. {eq}f(x, y) = 1 - y^2 {/eq} Surface Suppose if the implicit function is given and we need to plot the graph, the first step is to equate some variables and see if we can simplify the equation and reduce it to some standard form or not. If...

P(x)=−2x(x−2)2 Graph of Function:When the two variable functions is plotted in the Cartesian plane, then it may have extrema point, the inflection point, x-intercepts, and y-intercepts etc. Also, we can make use of calculus to find the critical points which help in plo...
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...

我们定义:一个整数能表示成a2+b2(a,b是整数)的形式,则称这个数为“完美数”.例如,5是“完美数”.理由:因为5=22+12.再如,M=x2+2xy+2y2=(x+y)2+y2(x,y是整数),所以M也是“完美数”.解决问题:(1)请你再写一个小于10的“完美数” 4;并判断40是否为“完美...
