Answer
The correct answer is C.
is a reflection of
over the line
.
Solution
To analyze the functions
and
, we need to understand their graphs and how they relate to each other.
-
Graph of
: - This is a parabola that opens upwards with its vertex at the point
. The graph is symmetric about the -axis.
- This is a parabola that opens upwards with its vertex at the point
-
Graph of
: - This is also a parabola that opens upwards, but it is expressed in terms of
. If we rewrite it in terms of , we can express it as . This means that for each value of , there is a corresponding value of .
- This is also a parabola that opens upwards, but it is expressed in terms of
Now, let’s analyze the options:
A.
is a reflection of
over the
-axis.
- This is incorrect. The graphs are not reflections over the
-axis; they are different representations of parabolas.
B.
is a reflection of
over the line
.
- This is also incorrect. The graphs do not reflect over the line
.
C.
is a reflection of
over the line
.
- This is correct. The graph of
can be obtained by reflecting the graph of over the line .
D. Deflection of
over the
-axis.
- This is incorrect. The graphs do not reflect over the
-axis.
Thus, the correct answer is:
C.
is a reflection of
over the line
.

The graphs of
and
actually represent two different perspectives on parabolic functions. While
describes a standard upward-opening parabola that moves up 4 units on the y-axis,
treats y as the independent variable, effectively flipping the traditional x-y roles, resulting in a sideways-opening parabola with the vertex at (0, 4).
Now, when you consider the reflections, the relationship isn’t a simple one. The correct description would note that if you consider them in their respective coordinate systems,
would be completing the transformation of
when solving for y. Essentially, the graphs can depict a symmetry over the line
when you interpret both functions in terms of their intersections and overall shapes.
