15.60 | 2.40 | | 6.30
You reflect a function with respect to the 
axis by changing its sign.
In fact, if you consider the two alternatives
and 
you can see that you're choosing opposite outputs for the same inputs.
In other words, one graph will be made of points like 
, the other of points like 
And the transformation
is exactly a reflection with respect to the axis.
4. However, you can do this in a Calculator.
