nothing
There is no equation (nor inequality) in the question so there can be no graph - with or without an axis of symmetry.
Answer this question… What is the line of symmetry of the graph of the equation ? A. x = -2 B. x = -4 C. x = -16 D. x = -8
I regret that I can see no function shown.
Symmetry is important as it can test whether the student is alert
the line of symmetry would occur at x=0
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
This graph fails the vertical line test at x = 3This graph is not the graph of a function.
-2
It is the axis of symmetry.
bar graph
A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.
X=-b/2a
