Hello, on these two problems I'm really confused on how to get here. I'm really lost, any explanation would be helpful, or even some resources to learn from.

Question 3 10 I 10 pts Let K have an exponential distribution with mean of 1. Consider the transformation '1' = explX), and determine the density function of Y. Question 4 10 I 10 pts Let K have an exponential distribution with mean of 1. Consider the transformation '1' = explX), and determine the values of y for which the density function of Y is non zero
