If f(x)=3x5−10x3+5, on what intervals is f″(x)> 0?

enter the (disjoint) interval(s) below using 'u' for union, '"nf" for [infinity], and "-inf" for −[infinity] if necessary.

Step-by-step explanation:

we are given an algebraic function in x, such that

To find when second derivative >0

For this let us find first and second derivative by successive differentiation.

when ii derivative >0 we have

60x^3-30>0

f"(x)>0 in

253
