The given function is
. This is a transformation of the parent square root function,
. Therefore, option A is correct
To determine how the function has been transformed, we look at the changes to the variable
and the constant term outside the square root.
1. The
inside the square root has been replaced by
. This indicates a horizontal shift. Since it is
, the shift is to the right by 2 units. If it had been
, the shift would have been to the left by 2 units.
2. The
outside the square root indicates a vertical shift upwards by 1 unit. If it had been
, it would indicate a shift downwards by 1 unit.
Combining these two observations, the transformation of the function
to
involves a translation 2 units to the right and 1 unit up.
Therefore, the correct statement describing the transformation is:
A. The graph of
is translated 2 units to the right and 1 unit up.
