3) 1.5, 2.5, 2.5
Step-by-step explanation:
1)
The function that we have in this problem is
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:
The to find the value of the 2nd iteration, we just substitute this value into the expression of the function, and we get:
Finally, the 3rd iteraction is given by:
2)
Here in this problem the function that we have to use is
The initial value is
So the first iteration is given by
To find the 2nd iteration, we substitute this value into g(x) again:
Finally, to find the 3rd iteration, we substitute this value into g(x) again:
3)
The function in this problem is
The initial value is
x = 0.5
So, the first iteration is:
The second iteration is given by
Finally, the 3rd iteration is
Answer:
The third picture
Step-by-step explanation:
Solve for x in both equations
2x<6
Divide both sides by 2:
x<3
3x+2>-4
Subtract 2 from both sides:
3x>-6
Divide both sides by 3:
x>-2
There is this trick you can use when x is on the left side of the equation to find out which way to shade in you graph. Keep in mind this is only for the left side, it will not work if your variable is on the right.
When the symbol is facing left < then shade left, imagine it is pointing which way to shade. x<3 is represented by the 3 picture on the left. When the symbol is facing right > then shade right, again it is pointing which way to shade. x>-2 is represented by the 3 picture on the right.
The circles are not filled in because the symbol is < and > rather than . When it is greater than or equal to or less than and equal to (represented by the line under the symbol), then the circle is shaded in.
