If , then the 4th derivative of at x=0 is what ?

Simply appply the chain rule over and over again
f'(g(x))=f'(g(x))g'(x)

first derivitive would be f'(x)=4(2x+1)³(2) or 8(2x+1)³
2nd derivitive would be 24(2x+1)²(2) or 48(2x+1)²
3rd derivitive would be 96(2x+1)2 or 192(2x+1)
4th derivitive would be 192(1)(2) or 384
at x=0, the derivitive is 384

Just a question- could you organize the data better? i just cannot tell which number are for which bakery. i will be happy to answer this question if you could do this for me! : )
