Which graph best shows an inverse relationship?

The correct graph is Image 2.

Explanation:

Direct relationship is defined as the relationship in which if one function increases, the other also increases and vice-versa.

Inverse relationship is defined as the relationship in which if one function increases, the other decreases and vice-versa.

First graph is the graph of a linear function with a negative slope. This is also known as direct relationship graph.

Second graph is the graph of an inverse relationship.

Third graph is the graph of logistic graph.

Fourth graph is the graph of linear function with a positive slope. This is also known as direct relationship graph.

Hence, the correct graph is Image 2.

The graphs can be described as

So in case of inverse relationship we will obtain a curve not straight line

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
