I can't do this questio although my teacher helped me I still can't do it, please check.
y''= x+2 and if x=3, y'=7 and y=12.
(hint: evaluate constants as they are created)
My failed attempt:
y'=(x^2)/(2) + 2x + C = 7 when x=3.
9/2 + 6 + C=7
And I also know that (x^3)/(6) +x^2 +7 = 12
That is the second derivative.
I hope what I have written makes sense.
Wait where did the K come from, sorry I dont follow.
