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) 

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
