1: What is an inverse function? Give an example.?
2: What is a composite function? Give an example.?
3: The inverse of a function is a set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function. Example: f(x)=x-4
y=x-4
x=y-4
x+4=y
f-1(x)=x+4 is this correct explain why?
