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
