hello, so i'm stuck on this problem where im given the function with constants and the point it passes through and the second derivative and first derivative at that point but i cant figure out how to find the constants.... please help...
so here is the question,
The curve of y= x^4 + ax^2 + bx + c, passes through the point ( -1 , -8) and at that point f ''(x) = f '(x) = 6. find the values of a, b, and c and sketch the curve.
i dont get what f ''(x) = f '(x) = 6 actually means so please clear it up for me as well as how to find the values of a,b,and c.
thanks in advance
