The function is increasing is interval for which the value of function increases with increase in value of x. So function is increasing in,
[tex](-4,-2)[/tex]
The function is decreasing in interval in which value of function decreases with with increase in value of x. So function is decreasing in,
[tex](-\infty,-4)\cup(-2,\infty)[/tex]
The function is defined for value of x lie between negative infinity and positive infinity. So domain of the function is,
[tex](-\infty,\infty)[/tex]
As it can be observed that function is approaching inifity at ends. So range of the function is,
[tex](-\infty,\infty)[/tex]
