1. POLYNOMIAL
FUNCTIONS
2nd Quarter

2. Introduction
1.What is a polynomial
equation?
2.Can you give an
example?
3.How about a
polynomial function?

3. Polynomial
Function
A function of the form
y= anxn+an-1xn-1+an-2xn-
2+…+a1x+a0,an≠
0,
where n is a
nonnegative integer.

4. Forms of
Polynomial
Function
1. Standard form. If the terms of
polynomial function are written in
decreasing powers of x, a polynomial
function is written in standard form.
2. Factored form. Polynomials may
also be written as the product of
irreducible factors. Ex: y= x4+2x3-
x2+14x-56 in factored form y=
(x2+7)(x-2)(x+4)

5. Seatwork
Factor the following
completely:
1. (x − 1)(𝑥2 − 5𝑥 + 6)
2. 𝑥3
+ 3𝑥2
− 4𝑥 − 12

6. Question
From the factors on the
activity, how will you get
the values of x?

7. Remember
• Polynomial function is a
polynomial equation that
deals with two variables.
• The values of x in the
polynomial functions are
known as the x-intercepts
because these are the
values of x when y=0.

8. Question
How is polynomial
equation different from
polynomial function in
terms of:
a. Definition?
b. Values of x?

9. Seatwork
From the same given on
the activity, find the y-
intercept.
