Question 12
a.

Show that the equation x3+4x=1x^3 + 4x = 1x3+4x=1 has a solution between x=0x = 0x=0 and x=1x = 1x=1.

b.

Starting with x0=0x_0 = 0x0​=0, rearrange the equation x3+4x=1x^3 + 4x = 1x3+4x=1 to give an iteration formula and use it twice to find an estimate for the solution to x3+4x=1x^3 + 4x = 1x3+4x=1
