Start by looking at simpler versions:

Suppose P is polynomial of degree 2, P(0)= 1, P(1)= 2, P(2)= 4. Since P is of degree 2 we can write it as [itex]P(x)= ax^2+ bx+ c[/itex]. Use P(0)= 1, P(1)= 2, P(2)= 4 to find a, b, and c. What is P(3)?

Suppose P(x) is a polynomial of degree 3, P(0)= 1, P(1)= 2, P(2)= 4, P(3)= 8. Since P is of degree 3, [itex]P(x)= ax^3+ bx^3+ cx+ d[/itex] use the values at x= 0, 1, 2, and 3 to find a, b, c, and d. What is P(4)?

Do you see a pattern? Can you show that this pattern is correct?
 

FAQ: Calculating P(2013) of Polynomial P(x) of Degree 2012

What is the degree of P(x)?

The degree of a polynomial is the highest power of its variable. In this case, the degree of P(x) is 2012.

What is the coefficient of x^2013 in P(x)?

The coefficient of x^2013 in P(x) is the number multiplied to x^2013. This can be found by looking at the term in the polynomial that contains x^2013. If there is no term with x^2013, then the coefficient is 0.

How do you calculate P(2013)?

To calculate P(2013), simply plug in the value of 2013 for x in the polynomial P(x) and then simplify the resulting expression. This will give you the value of P(2013).

What is the leading coefficient of P(x)?

The leading coefficient of a polynomial is the coefficient of the term with the highest degree. In this case, the leading coefficient of P(x) is the coefficient of x^2012.

What is the significance of calculating P(2013) for a polynomial of degree 2012?

Calculating P(2013) allows us to find the value of the polynomial at a specific point, in this case, x = 2013. This can be useful in various applications, such as finding the roots or zeros of the polynomial or analyzing its behavior at that particular point.
