You can model the population of a certain city between 1945-2000 by the radical function P(x) = 55,000 square?

1. You can model the population of a certain city between 1945-2000 by the radical function P(x) = 55,000 square root x - 1945. Using this model, in which year was the population of that city 165,000? A. 1948 B. 1951 C. 1954 D. 1957 2. What is the inverse of f if f(x) = ^3 square root x - 4? A. f^-1 (x) = x^3 + 64 B. f^-1 (x) = x^3 + 4 C. f^-1 (x) = 4 - ^3 square root x D. f^-1 (x) = 1 over ^3 square root x - 4 PLEASE GIVE EXPLANATIONS FOR THESE QUESTIONS SO I KNOW HOW TO DO THEM IN THE FUTURE.
