Function g is perpendicular to function f. Function fis represented by f(x) = x + 9 Two points that lie on function g are represented by (a + 3,5a + 6) and (2a + 6,7a + 2). What is the value of a?

The graph of f(x) = |x| is transformed to g(x) = |x + 11| - 7. on which interval is the function decreasing?
