Question

Given f''(x)=2x+5
and f'(0)=-3 and f(0)=4.
Find f'(x)

Answer 1

y'=x^2+5x-3???

Answer 2

Yes that's correct, thank you. Can you please tell me how you found it??

Answer 3

first find the integral of f"(x)= f'(x)
then, plug in x=0, and f'(x)=-3, and solve for c, which is came from the integral of f'(x)....

Answer 4

Thanks a lot!
