so like ive asked people, looked on the internet, and i found nothing :L
so hopefully, some of you are smarter
and and and, could you also explain how you got to the answer

a) y= 7 OVER (4-3x)
differentiate, and answer as a fraction without a negative indicie

b) y= 4 OVER (3x-1)^5
same as above

c) y= - 5 OVER (x+1)^3
same as above
NOTE: that there is a negative sign in front of the entire fraction


THANKS HEAPS GUYS !

Re: okay BOS, show me what your made of, by helping me with this CALCULUS QUESTION !

y = 7(4-3x)^-1
multiply by the power and the derivative of the bracket and reduce the power by 1.
power = -1, derivative of the bracket = -3, new power = -2
y' = 7(-1)(-3)(4-3x)^-2
y' = 21 / (4-3x)^2

sorry, i don't know how to use latex. lol -_-
follow those steps and try the other two.
