If f(x) = 3x^2 -Bx + 4 and f(-1) = 12, what is the value of B?
Must I plug -1 for x in the given trinomial?
Why is 12 given as a result in terms of f(-1)?
let's say you want to find a cubic polynomial that will go through certain points. you could say that the polynomial is of the form y = ax^3 + bx^2 + cx + d, and use properties like these to find the particular function
