With these 2 questions. will give brainliest to best asnwer

First Image:
f(x) means limit of f(x) as x approaches to 2 from negative side i.e. the left side. As seen from the graph, as we approach 2 from left hand side, the graph of f(x) approaches 3.
So, f(x) = 3

means limit of f(x) as x approaches to 2 from positive side i.e. the right side. As seen from the graph, as we approach 2 from right hand side, the graph of f(x) approaches -3.
So, f(x) = -3

Second Image:
f(x) means limit of f(x) as x approaches to 3 from negative side i.e. the left side. As seen from the graph, as we approach 3 from left hand side, the graph of f(x) approaches -1.
So, f(x) = -1

The answer is biodiversity resulting from new ancestors.
