Question

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

Answer 1

Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping
`f(x)\mapsto -f(x)`

So, if you have a x/y values table, you simply have to change sign to all the values in the y column.
