To determine the transformations needed to graph the function
using the graph of
, we can compare the given function with the standard form of a quadratic function, which is
, where
represents the vertex of the parabola.Comparing
with the standard form, we can see that:- The coefficient 4 in front of
indicates a vertical stretch by a factor of 4.- The term
inside the squared parentheses indicates a horizontal shift 2 units to the right.- There is no constant term added or subtracted outside the squared parentheses, so there is no vertical shift.Therefore, the transformations needed to graph the function
using
are:- Shift the graph 2 units to the right (option D)- Stretch the graph vertically by a factor of 4 (option F)So, the correct options are D and F.
