In a composition, the first transformation produces an image upon which the second transformation is then performed.?The symbol for a composition of transformations is an open circle.??The notation??is read as a reflection in the?x-axis?following?a translation of?(x+3,?y+4).? 7048512064900Sample Test Questions:1) 1270001333500524256041275156210125730002) 1276358255003689985635000156210-31750003)232409508000128270990604) 6096013335003451860508000172695-692415) right20955002038352095500175260895356)right6985002324109525001358901295407) 348996011430001752601174750034847711270000137160155575008) 1752601397000174625742959) 352806010668000194309571500117475117475003766185996950010) 2419356349900HW#48: Name ______________________________ Date: _______________ Per. ______________1) On the coordinate plane belowA) graph with coordinates B) Sketch the image of , namely after rotation 180o about the origin.C) Sketch the image of , namely after dilating with a scale factor of 2 with center of dilation at the origin.3642360254000D) What single transformation would map onto381022669500 ?2) Describe the sequence of transformations that map onto 270891069850032385698400 ................
