Solution:
We have:
f(x) = √x
g(x) = 7x + b
y = f(g(x)), Given point on the graph (x, y) = (4, 6)
Use: f(x) = √x
f(g(x)) = √(g(x))
y = √(7x + b), x = 4, y = 6
6 = √(7(4) + b)
6² = (7(4) + b)
36 = 28 + b
36 - 28 = b
8 = b
b = 8

Answer:
(-9, π/5 + (2n + 1)π)
Step-by-step explanation:
Adding any integer multiple of 2π to the direction argument will result in full-circle rotations, which are identities, so this family is equivalent to the give coordinates:
(9, π/5 + 2nπ), for any integer n
Also, multiplying the radius by -1 is a point reflection, equivalent to a half-turn rotation. Then add π to the direction for another half turn, and the result is another identity. So this too is equivalent to the given coordinates:
(-9, π/5 + (2n + 1)π), for any integer n
