Question 23

The curve C C\,C with equation y=exy = e^xy=ex meets the line L L\,L with equation y=2x+10y = 2x + 10y=2x+10 at the point RRR.

a.

Show that the x x\,x coordinate of R R\,R satisfies x=ln⁡(2x+10)x = \ln(2x + 10)x=ln(2x+10).

[2]
b.

Use the iteration formula xn+1=ln⁡(2xn+10)x_{n+1} = \ln(2x_n + 10)xn+1​=ln(2xn​+10) with x0=3x_0 = 3x0​=3 to find, to 3 decimal places, the values of x1x_1x1​, x2 x_2\,x2​ and x3x_3x3​.
