Which table of values could be used to graph g(x), a reflection of f(x) across the x-axis?

For this case the first thing you should know is that a reflection on the x axis is given by the following rule:
 (x, y) > (x, -y)
 We observe that the values of y are the same but negative.
 We have then that the table is:
 third and fourth table attached (from left to right) 
 
 A table of values that could be used to graph g (x), a reflection of f (x) across the x-axis is:

Idon’t feel like doing the math but you need to do 2.24 divided by 7
