s the cnrFe called the parabola,—one of the classknown as conic sections. The values of y are givento the second decimal, that it may be seen the graphis not a straight line; for while the values of x pro-ceed bj equal increments of 1. the successive incrementsof y are 2, -83, -63, -54, -47, -43,… … a:2 + 2lx-3y-5 = 0. Here i= -Ix ^ 3j/-2,. E\ddentlyy cannot be less than - 2; i.e., the graph cannot be Equations and Loci. 31 more than 2 units below the axis of x. With a tableof square roots we readily obtain the following pairsof values : y= -2^ x= -l; y=-l,x=73or- 273; y =0, x = 1*45 or -…
