Remainder Theorem
If a polynomial f(x) is divided by (x-c), the remainder is f(c)
Factor Theorem
A polynomial f(x) has a factor (x-c) if and only if f(x) = 0
At most n-1 turning points
A polynomial with degree n has:
A polynomial with odd degree:
Has opposite end behavior on the left and right
A polynomial with even degree:
Has the same end behavior on the left and right
If the multiplicity is odd, it crosses the x-axis at the intercept
When will a polynomial bounce at a zero? When will it cross it?
Intermediate Value Theorem
If f(a) > 0 and f(b) < 0 then there is a real zero between a and b
Rational Zero Theorem
All the rational zeros of a polynomial f(x) will have the form ±p/q where q is a factor of the leading coefficient and p is a factor of the constant term.
IF the leading coefficient of the polynomial is positive:
How do we know if a (positive) number is an upper bound of a polynomial?
How do we know if a (negative) number is a lower bound of a polynomial?
IF the numbers in the bottom row alternate in sign, it is a lower bound
Descartes' Rule of Signs
The number of positive real zeros of f(x) is equal to the number of sign changes in a f(x) decreased by an even integer
Fundamental Theorem of Algebra
If P(x) is a polynomial of degree n>or equal to 1. then P(x)=0 has exactly n roots, including multiple and complex roots.
Linear Factor Theorem
Every polynomial f(x) of degree n can be written as the product of its leading coefficient and n zeros of the form (x-c)
Conjugate Pair Theorem
If a+bi is a zero of a polynomial with real coefficients, a-bi is also a zero.
