Math Tutoring on Graphing the Square Root Function with Transformations

 

Square root parent function is the simplest form of the square root function, or f(x) = √x. 

 

Vertical Translation                              Horizontal Translation

y = √x + d                                                 y = √x - c

d > 0: shifts up IdI units                        c > 0: shifts to the right IcI units

d < 0: shifts down IdI units                   c < 0: shifts to the left IcI units

 

Vertical Stretch and Compression            Horizontal Stretch and Compression

     y = a√x                                              y = √bx

IaI > 1: vertical stretch                                IbI > 1:horizontal compression(shrink)

IaI < 1: vertical compression (shrink)       IbI < 1: horizontal stretch

a < 0: reflection in x-axis                            b < 0: reflection in y-axis
