1. Differentiate (use appropiate symbols)
a) y = x ⁹
y'=9x ⁸

b) f(x)=5x ³ - 3x + 6
f'(x)=15x ² -3

c) y = 4x ^-5
y'=20x ⁴

2. d/dx (-12x)
f"(x) = -12

3. differentiate
a) y = (2x+3) ⁴
y' = 4*(2x+3 ³*2

a) f(x) = x ² ( 2x+3) ⁴
f'= 2x+4*(2x+3) ³*2

Thanks,

I think in part the online test allows only for the correct answer and I do not have enough knowledge to put it in correctly, in answering the question. That if I try I am not told correct parts or inccorect parts and I am given knew equations if I fail. Thus I must investigate the right answers since I could be either a little wrong or majorly wrong etc. Thanks.

Actually there is a lot of help i need with derivatives and this topic, like tangents, intervals and all sorts of things in this test. Any suggestion, when I read the info in 2 hours i gain no understanding and no closer to solving it.
