how do you have a reflection in the x axis, if the shape is already partially in the third and second quadrent of the graph
IgorLugansk [536]

Its a reflection over an x-axis, whats "positive" goes "negative" and whats "negative" goes "positive" with respect to y.

If a shape S is a subset (made of P_2\cup P_3 of quadrants Q_2,Q_3 then the part P_2 that lies in the second quadrant gets mapped to Q_3 and part P_3 that lies in third quadrant gets mapped to Q_2

Hope this helps.

h. Check attached picture

I) i. Are A and B mutually exclusive? Are A and C mutually exclusive? Are B and C mutually exclusive?

A and B are mutually exclusive if AnB = ∅

Check :

AnB = {1TT}

Hence, A and B are not mutually exclusive
