Trying to understand piecewise functions. Can you please explain each letter to me. I'm confused on a) How do you decided what values to plug into the 2 equations? And also what if there is a x=1 as an equation? C) why is the domain all real numbers? D) How do I find the range? E) why is F(x) continuous Can you explain in detail this one please my teacher didn't talk about continuous. Thanks in advance for the help!
