Question

h(x)= -36x^5-270x^4-480x^3-20

 

Can you show me how to find the intervals where h is increasing and decreasing?

 

Can you show the values where h has a relative maximum and minimum?

 

I had (-oo, -4) for increasing and it should have been (-4,-2)

I had (-4,0) and it should have been (-oo,-4),(-2,oo)

I had -4 for relative maximum and it should have been -2

I had -2 for relative minimum and it should have been -4

 

Could you show me how to do with a sign chart
