Step-by-step explanation:
First Let x0 be 1 and x1 be 3
F(x0) = x3 – 4x -9
=1– 4– 9
= -12 < 0
F(x1) =27 – 12 – 9
=6> 0
Therefore, the root lies between 1 and 3
Now we try with x2 =2
F(x2) = 8 – 8 – 9
= -9 < 0
Therefore, the root lies between 2 and 3
X3
= (x1+x2)/2
=(3+2)/2
= 2.5
F(x3) = 15.625 – 10 – 9
= - 3.375 < 0
Therefore, the root lies between 2.5 and 3
X4
= (x1+x3)/2
= 2.75
