Let f(x)=x^2- 3. 1. Show that [0, 2] is a bracketing interval for f 2. Carry out 3 iterations of the bisection method applied to
Papessa [141]

Answer:

root estimate = 1.75

error bound = 0.25

Step-by-step explanation:

f is a polynomial, so it is continuous in R (real numbers). Then you can use Bolzano's theorem.

f(0) = -3.1 < 0

f(2) = 4 - 3.1 = 0.9 > 0

Then there exists c in [0, 2], for which f(c) = 0

In the bisection method you generate a sequence x_n of approximations of a root. If you have a bracketing interval [a, b], such that

f(a) and f(b) have opposite signs, then you use  approximate the root as x_n = \frac{a+b}{2}

In this case:

x_0 = 1

f(0)

Then:

x_1=1.5\\f(1.5)0\\

x_2= \frac{(1.5 + 2)}{2}= 1.75

The error bound is half the width of the interval [1.5, 2]

|error| < 0.25

Ryker is given the graph of the function
Lena [83]
You can just set y=0 and solve for x.  when you do this you should get 1/2x^2=4
x^2=8
x=2.8 and -2.8 ( you have both a positive number and negative number since (-2.8)^2=(2.8)^2 =8
I hope this helps
