1) 6, 18, 54
2) 5/3, 14/9, 41/27
3) 1.5, 2.5, 2.5
Step-by-step explanation:
1)
The function that we have in this problem is
[tex]g(x)=3x[/tex]
We want to find the first 3 iterations.
The initial value is:
x = 2
To find the value of the 1st iteration, we just substitute this value into the expression of the function, and we get:
[tex]g_1(x)=3x=3\cdot 2 = 6[/tex]
The to find the value of the 2nd iteration, we just substitute this value into the expression of the function, and we get:
[tex]g_2(x)=3\cdot g_1(x)=3\cdot 6 = 18[/tex]
Finally, the 3rd iteraction is given by:
[tex]g_3(x)=3g_2(x)=3\cdot 18=54[/tex]
2)
Here in this problem the function that we have to use is
[tex]g(x)=\frac{1}{3}x+1[/tex]
The initial value is
[tex]x=2[/tex]
So the first iteration is given by
[tex]g_1(x)=\frac{1}{3}\cdot 2 + 1 = \frac{5}{3}[/tex]
To find the 2nd iteration, we substitute this value into g(x) again:
[tex]g_2(x)=\frac{1}{3}g_1+1=\frac{1}{3}\cdot \frac{5}{3}+1=\frac{5}{9}+1=\frac{14}{9}[/tex]
Finally, to find the 3rd iteration, we substitute this value into g(x) again:
[tex]g_3(x)=\frac{1}{3}\cdot \frac{14}{9}+1=\frac{14}{27}+1=\frac{41}{27}[/tex]
3)
The function in this problem is
[tex]g(x)=-|x-2|+3[/tex]
The initial value is
x = 0.5
So, the first iteration is:
[tex]g_1(x)=-1|0.5-2|+3=-1|-1.5|+3=-1\cdot 1.5 +3=-1.5+3=1.5[/tex]
The second iteration is given by
[tex]g_2(x)=-|g_1-2|+3=-|1.5-2|+3=--0.5+3=2.5[/tex]
Finally, the 3rd iteration is
[tex]g_3(x)=-|g_2-2|+3=-|2.5-2|+3=-0.5+3=2.5[/tex]
