The range of the function is
Multiply first line by :
Subtract from second line:
Multiply last line by 4:
Add first and third line:
Multiply second line by 4 and third line by 17 (to get LCM 136):
Add the two equations:
, therefore the system has no solution.
The y-coordinates of the graph of are shifted upwards by 2 points.
