Behaviorism is a psychological approach which is based on belief that all human actions and responses may be explained through the concept of reward and punishment. In studying language development, in kids for examples, parents may give reward if the kid is able to speak a certain word. 

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing 

Iwould say b but i’m not so sure
