Why is surface area so important?

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer, that would be nice

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)
