Question

Let F(x) = 1/sqrt(x+1). Sketch carefully the graph of y = F(x) for 0 <= x <= 2. Add the line y = x to your diagram, and indicate the location of the root r of the equation F(x) = x. use algebra
to show that x = r also solves the equation x^3 + x^2 = 1. Use the method of simple iteration
to calculate r to 5 significant figures.

Answer 1

Need help with using x=r to solve x^3 + x^2 = 1.
