Answer:
The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.
Explanation:
The equation of circle is given as:

also the graph of the function g(x) is given by:
We are given a set of values in a table as:
x g(x)
−4 −4
−2 −2
2 2
Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:
y=mx+c; where m denotes the slope of the line and c denotes the y intercept.
when x=-4 g(x)=y=-4
-4=-4m+c
also when x=-2 then y=g(x)=-2
-2=-2m+c
on solving the above two equations using elimination method we get,
m=1 and c=0
hence, y=g(x)=x
Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.
Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.
