I'm REALLY having trouble with these two questions!

1. If the point (4, 5) is on the graphof y=f(x), the graph ofy=f-1(x) - 9 will change this point so that they-coordinate is...

2. Thegraphofy=f(x) contains the point (6, -10). Ify=f(x) is transformed toy= -4f(-6x - 15) + 15, the point (6, -10) is changed to the point (p,q). What are the values of p and q?

Thank you SO much for the help, I really appreciate it.
