math help: functions and derivatives?
f ' (x) = 5x^4
what is f(x) if f(3) = 197
- Iggy RockoLv 73 weeks ago
f '(x) = 5x^4
f(x) = x^5 + c
197 = 3^5 + c
197 = 243 + c
c = -46
f(x) = x^5 - 46

What function is such that its derivative is 5x^4?
Try a few potential candidates. You will find it.
Once found, you know that adding a constant won't change its derivative.
Answer the above & we will take it from there if need be.
Hint: Whats the derivative of x? Of x² ? Of x^3 ? Of xⁿ ?
