Answer
Squeeze theorem states that when a function b(x) is less than or equal to c(x) and greater than or equal to a(x) for all x values, then at the x value when a(x) equals c(x), b(x) must equals to a(x) and b(x).
Work Step by Step
It is used to help find limits of the function that is being "squeezed" (in between the other two).
