[itex]y=1/squareroot(x+1)[/itex]
[itex]y=x[/itex]
Sketch the two graphs, and indicate on your graph the location of the root r of the equation [itex]1/squareroot(x+1)=x[/itex]. Use algebra and show that x=r can also solve the equation [itex]x^3+x^2=1[/itex]. Calculate r to 5 significant figurees using simple iteration.
Im stuck in the part in bold. I can rearrange [itex]1/squareroot(x+1)=x[/itex] into [itex]x^3+x^2=1[/itex], but how do i show that x=r can solve the equation? Thanks.
