Given a circle described by the equation:
and a function g(x) given by the table
The function g(x) describes a straight line with the equation:
To check if the circle and the line intersects, we substitute the equation of the line into the equation of the circle to see if we have a real solution.
i.e.
When x = 6, y = 2(6) - 20 = 12 - 20 = -8 and when x = 10, y = 2(10) - 20 = 20 - 20 = 0
Therefore, the circle and the line intersect at the points (6, -8) and (10, 0).

Although the question's print is not clear, to the best of my knowledge, as I can see, We are given that:
and
No, we know that, by definition:
Thus, for the functions r and s which are defined for all real numbers x, the answer to the question asked is:
