Step-by-step explanation:
For x = 1
(1)
For x = -3,
(2)
For x = 3,
(3)
Let's add Eqn(2) and Eqn(3) together to eliminate b:
(4)
Next, multiply Eqn(1) by 3 and then add to Eqn(2) to get
(5)
Then we want to eliminate c by multiplying Eqn(4) by -2 and then adding to Eqn(5) and we will get
Now that we have the value for a, we can use either Eqn(4) or Eqn(5) to solve for c and we will get
Using the values of a and c on Eqn(1), we find that so therefore, our function f(x) has a form
