What they are really asking you is for every value r that you are given. Substitute that vale for r in the given function F(r).. Pronounced the Function F of r.
F(r) = r2+5 we know that r = x+1 soo now its called F at (x+1)<----->F(x+1)
F(x+1) = (x+1)2 + 5
r = 3x --------------->F(3x) = (3x)2 + 5
r = 1/x -------------->F(1/x) = (1/x)2 + 5
hope that helps some
