Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value -1, a 0 indicates no correlation; and a +1 indicates a perfect positive correlation.

indica que as duas variáveis movem-se em direções opostas, e que a relação também fica mais forte quanto mais próxima de menos 1 a correlção ficar. Duas variáveis que estão perfeitamente correlacionadas positivamente (r=1) movem-se essencialmente em perfeita proporção na mesma direção, enquanto dois conjuntos que estão perfeitamente correlacionados negativamente movem-se em perfeita proporção em direções opostas.

Describe how the graph of each function differs from the graph of f(x)=|x|. Then determine the domain and range.
Brilliant_brown [7]

A. We can compress the graph of the function f(x)=|x| in the y-direction by multiplying the whole function by a constant C, such that 0 Since 0, the graph of the function g(x)= 0.6|x| is obtained from the graph of the function  f(x)=|x| by compression in the y-direction.

B. We can stretch the graph of the function f(x)=|x| in the y-direction by multiplying the whole function by a constant C, such that C>1. Since 4>1,, the graph of the function g(x)= 4|x-3| is obtained from the graph of the function  f(x)=|x| by compression in the y-direction and translation 3 units to the right.

C. We can flip the graph of the function  f(x)=|x| upside down by multiplying the whole function by −1, then translate 1 unit to the left and 5 units up. Then we will get the function g(x)=-|x+1|+5.
