What is the focus of community psychology

The focus of community psychology is to improve the quality of one’s life through prevention and second order change.  

Explanation:

             Community psychology travels beyond an individual approach and integrates “social, cultural, environmental and international influences” to promote positive change. Additionally, it makes health and personal responsibility at the individual and system levels. It uses different psychological and external perspectives to address the attitudes and behavior of communities, their relationships and the people involved.  

             Community psychologists try to promote healthy and empowering groups and communities. They use concepts and knowledge from various disciplines, such as social, ecology, and intercultural psychology. Second-order change means paying attention to the system and structures that are involved in the problem to suit the human-environment good.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
