d) whenther there the limit is going to infinity like that
take the large term on the top and the largest one on the bottom
so;
4x^5/12x^2 =
basically if you continued to plug it in it would give you
4x^5/12x^2
eventually 12x^2 would = 24 because you would get 12x^2 to 24x^1, take the dervative = 24
for the top it would go from 4x^5; 20x^4; 80x^3
then you would have 80x^3/24
plug in infinity for x
infinity/24
