If the graph of the function
in the
-plane contains the points
,
, and
, which of the following CANNOT be true?
(A) The graph of
has a maximum value.
(B)
for all points
on the graph of
.
(C) The graph of
is symmetric with respect to a line.
(D) The graph of
is a line.
(E) The graph of
is a parabola.
The correct answer is D
Explanation
If the graph of the function
, which contains the points
,
, and
, were a line, then the slope of the segment connecting the points
and
would be the same as the slope of the segment connecting the points
and
. However, the slope of the segment connecting the points
and
is
, and the slope of the segment connecting the points
and
is
. Therefore, the graph of
cannot be a line.
The statements in the other four options could be true. For example, if the equation of
were
, then the graph of
would contain the points
,
, and
. The graph of
would be a parabola symmetric with respect to the line with equation
. The maximum value of
would occur at the point
, and
would be true for all points
on the graph of
.
