If dy/dx is 2x-7 in an initial value problem, and y(2) = 0, how do I go about solving this? I tried plugging in 0 for x, but I don't think it's quite that simple...

ok,so it's x^2 - 7x. Um, Idk what to do after. Plug 2 in?

What are you solving for?

It just says "solve the initial value problem" and the answer is an equation, but I have no idea how it got there. Answer is: x^2 -7x +10. So I guess I'm looking for C using y(2)=0?

from x^2 - 7x +C from integrating original prob.

So you are to solve for C Hmmm. 0=2^2 -14 + C substituting 2 for x 0=4-14+c C=10 Would that work?
