7. DEFINITION OF TERMS
A polynomial function is a function in the form
π·(ΰ’) = ππΰ’π + ππβπΰ’πβπ + ππβΰ«ΰ’πβΰ« + β―+ ππΰ’π + ππ,
where π is a nonnegative integer, n as a positive integer implies that:
a. n is not negative
b. n is not zero
c. n is not a fraction
d. n is not a radical, and
e. n is not imaginary
π0, π1, β¦ , ππare real numbers called coefficients, πππ₯π is the leading
term, ππ is the leading coefficient, and π0 is the constant term.
8. NOTE
Polynomials may also be written in
factored form and as a product of
irreducible factors, that is a factor
can no longer be factored using
coefficients that are real numbers.
The function π¦ = π₯4 + 2π₯3 β 13π₯2 β
10π₯ in factored form is π¦ = (π₯ β 5)(
π₯ + 1)(π₯ + 2).
