looks like you are doing basic integration at the beginner's level.
Remember that integration is the "reverse" of differentiation.
So do this intuitively.
Ask yourself, "What terms did I have so that its derivative is 5x +3 ?"
Wouldn't that have been (5/2)x^2 + 3x + (some constant) ???
Now that would give you f'(x)
and you are given f'(-2) = 3 so you can find the constant.
Then repeat this to get f(x)
let me know what your answer is.
f"(x)=5x+3 and f'(-2)=-3 and f(2)=-5
Find f'(x) and find f(2).

I couldn't figure it out.
Ok, so I got the first part done. I got 5/2 x^2 +3x -7
Now I'm stuck on the f(2)= part.
I've gotten 5/6 x^3 +3/2 x^2 -7x + C
But what do I do from there?
