Using transformation sketch the graph of each of the following.
g ( x ) = - x^{2}
Solution
(a) Depending on the placement of the minus sign (that means it's outside the square & NOT within the square, or ( - x +2 ) it looks as we will be reflecting x^{2} around the x-axis. Thus, again, the means that all we do is vary the sign on all the y coordinates. Here is the sketch of this graph.
