25) Given the parent function ( ) | | write the function rule if the following transformations are done on
the parent function: vertical stretch by a factor of 2, reflection over the x-axis, horizontal translation of 3 units to
the right, and vertical translation of 4 units up.
26) Given the parent function ( ) √ write the function rule if the following transformations are done on
the parent function: vertical shrink by a factor of
, reflection over the y axis, horizontal stretch by a factor of 2,
and, and vertical translation of 3 units down.
Use your graphing calculator to solve the system of equations. Sketch the graphs, label the points of
intersection, and state the solutions. Round decimal answers to the nearest hundredth.
