Answer 1

You need to use Sandwich or Squeeze theorem as it's called.

It states that if there are three functions g(x), f(x) and h(x), such that, f(x) is sandwiched between the other two functions, then there exists a value 'c' such that limit of g(x), h(x) at c approaches a value L, then f(x) also approaches L.

Mark as the brainliest if you like :)
