Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
#1 is -32
#2 is -11
#3 is -5
#4 is 6
Horizontal compression by factor 2 will do following.
After compression graph of the function is going to be closer to line of symmetry of the parabola. Values of y are not going to change, but values of x will be 2 times closer to the the line of symmetry.
For our case , line symmetry x=2,
points are going to be 2 times closer to this line.
1st point (4, -3) converts into (3,-3)
2nd point (-4,5) converts into (-1,5)
