Best ResponseYou've already chosen the best response.0the original equation is +... but the derivative i believe would be negative right?//

Best ResponseYou've already chosen the best response.0(5x^2 +3) ^ 2 now take the derivitive of the inside function... {(5x^2 +3) ^ 2} x {10x} so the final answer is.. 10x(5x^2 +3)^2

Best ResponseYou've already chosen the best response.0is that the product rule?

anonymous

Best ResponseYou've already chosen the best response.0yeah, usually whenever i see something in the denominator i'll make it a negative exponent and solve it that way

Best ResponseYou've already chosen the best response.0f 'g + g'f {(5x^2 +3) ^ 2} x {10} + {20x(5x^2 +3) ^ 3} {10x} ok so i think that's what it is haha do you agree? i just used the product rule for it then the chain rule to find the derivitive of the ugly function

Best ResponseYou've already chosen the best response.0where did you use the chain rule at>

anonymous

Best ResponseYou've already chosen the best response.0to find the derivitive of this function: {(5x^2 +3) ^ 2}

Best ResponseYou've already chosen the best response.0isnt the chain rule for the function 10x(5x^2+3)^2?

anonymous

Best ResponseYou've already chosen the best response.0no, because in order to find the f'(x) of {10x} x {(5x^2+3)^2} you must assign one to be the g function and the other one the f function.. then you use f'g+g'f

Best ResponseYou've already chosen the best response.0i got (10)(5x^2+3)^2 + (10x)(10x)(20x)(5x^2+3)^3......before simplifying

Best ResponseYou've already chosen the best response.0what the heck did you do?

anonymous

Best ResponseYou've already chosen the best response.0that was the first derivative .. and to find the second derivative you have to take the derivative of f'(x)....

anonymous

Best ResponseYou've already chosen the best response.0so i took the product rule of f'(x).. and the chain rule after ...

anonymous

Best ResponseYou've already chosen the best response.0no, how did you find the derivitive of (5x^2 +3) ^ 2

anonymous

Best ResponseYou've already chosen the best response.0we already established that derivative ...

Best ResponseYou've already chosen the best response.0that was the 10x(5x^2+3)^2

anonymous

Best ResponseYou've already chosen the best response.0because for this you need to use the chain rule.. which means you would bring the 2 down and subtract one from the exponent (2)(5x^2 +3) ^3 then take the derivitive of the inside function.. 2(5x^2 +3) ^3 x (10x)

Best ResponseYou've already chosen the best response.0the equation is different than the orginial part of the problem

Best ResponseYou've already chosen the best response.0unless that was the first derivative the (5x^2+3)^2???

anonymous

Best ResponseYou've already chosen the best response.0ya that was teh first der.

anonymous

Best ResponseYou've already chosen the best response.0no. pretend it's a new function, don't even think about the first equation... f(x)={(5x^2 +3) ^ 2} g(x)={10x} Product rule.. f 'g + g'f {(5x^2 +3) ^ 2} x {10} + {20x(5x^2 +3) ^ 3} {10x}

Best ResponseYou've already chosen the best response.0yes that all makes sense.. i was considering the exponent "2" as g(x)..
