Hello(adsbygoogle = window.adsbygoogle || []).push({});

Could someone help me with this question please ?

A set of curves which all pass the origin, have equations :

y=f1(x)

y=f2(x)

y=f3(x)...... where f ' n(x) = fn-1(x) and f1(x) = x^2

1.) find the expression for fn(x)

2.) find f2(x) and f3(x)

I don't know where to begin, especially the first question .

thanks

roger
