endpoint a line segment at a 5 1 O b 15 9 O C 9 15 d 15 3 R3
Solution
Given is a graph.
Need to find the intercepts of the graph.Is it symmetric about x-axis.
Intercepts:
Intercept is a point where the graph crosses x-axis or y-axis.
If the graph crosses x-axis then it is x-intercept.
If the graph crosses y-axis then it is y-intercept.
By observing the graph, it only crosses x-axis.
So, x-intercepts of the graph are (5,0) and (-5,0).
A graph is said to be symmetric about x-axis if f(x) = -f(x) or y = -y
By observing the graph, this graph also have f(x) = -f(x)
Therefore, the given graph is symmetric about x-axis.
