Transforming Functions Part 1: Vertical Shifts
Review of Parent Graphs • Linear • y = x • Quadratic • y = x2 • Cubic • y = x3 • Absolute Value • Y = IxI • Square Root • Y = √x • Inverse • Y = 1/x
Vertical Shift: Linear Functions • y = x + 2 • y = x – 3 http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
Vertical Shift: Quadratic Functions • y = x2 + 1 • y = x2 – 4http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
Vertical Shift: Cubic Functions • y = x3 + 5 • y = x3 – 2http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
Vertical Shift: Absolute Value Functions • y = IxI + 3 • y = IxI – 5http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
Vertical Shift: Square Root • y = √x + 2 • y = √x – 3http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
Vertical Shift: Linear Functions • y = 1/x + 3 • y = 1/x – 2 http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
