Using transformation sketch the graph of each of the following.

                                            g ( x ) = - x²

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 x²  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.
