Suppose f is a polynomial such that f(0) = 47, f(1) = 32, f(2) = -13, and f(3)=16. What is the sum of the coefficients of f? I asked a helper and he said focus on what the question asks for. I still dont get how to do it.
Plus, this polynomial division problem is challenging for me.
There is a polynomial which, when multiplied by x^2 + 2x + 3, gives 2x^5 + 3x^4 + 8x^3 + 8x^2 + 18x + 9. What is that polynomial?

I just think I figured it out. Is it 5?
The inverse of
isThen, we just plug 137 for x into function q.
So,
equals 5.

Here's another question.
Let p(x) = 2x^3 - 113 and let q be the inverse of p. Find q(137).
Aren't you supposed to set 2x^3 - 113=137 or something like that?

f(2012)=f(2012+0)
Then this becomes 2012+f(0). We know that f(0) is 2 so f(2012) is 2014.

Let f be a function such that f(x+y) = x + f(y) for any two real numbers x and y. If f(0) = 2, then what is f(2012)? c
How are you supposed to solve this? Plus, I am really confused on how you are supposed to start this problem.

Find all values of p such that 2(x+4)(x-2p) has a minimum value of -18.
How do you work this problem?
