1. Use the Rational Root Theorem to find potential rational roots. 2. Use synthetic division to test the potential roots. 3. Factor the polynomial completely. 4. Solve for the remaining zeros (may involve the quadratic formula).

1. Find f(-x). 2. If f(-x) = f(x), the function is even. 3. If f(-x) = -f(x), the function is odd. 4. If neither, the function is neither even nor odd.

1. Group terms in pairs. 2. Factor out the greatest common factor from each pair. 3. If the binomial factors are the same, factor out the binomial. 4. Simplify.

1. Identify a, b, and c in the quadratic equation $ax^2 + bx + c = 0$. 2. Substitute into the quadratic formula: $x = frac{-b pm sqrt{b^2 - 4ac}}{2a}$. 3. Simplify. 4. If the discriminant ($b^2 - 4ac$) is negative, the roots are complex.

1. Identify the leading term ($ax^n$). 2. If n is even and a > 0, both ends go up. 3. If n is even and a < 0, both ends go down. 4. If n is odd and a > 0, left end goes down, right end goes up. 5. If n is odd and a < 0, left end goes up, right end goes down.

1. Calculate successive differences (first, second, third, etc.). 2. The degree is the number of times you need to take differences until you get a constant value.

Real Numbers: Can be plotted on a number line, no imaginary component | Imaginary Numbers: Involve the imaginary unit i = sqrt(-1), cannot be plotted on a standard number line

Even Functions: Symmetric about the y-axis, f(-x) = f(x) | Odd Functions: Symmetric about the origin, f(-x) = -f(x)

Even Multiplicity: Graph touches the x-axis and turns around, sign of f(x) does not change | Odd Multiplicity: Graph crosses the x-axis, sign of f(x) changes

X-intercepts: Points where the graph crosses the x-axis, y=0, represent real zeros | Y-intercepts: Point where the graph crosses the y-axis, x=0, represents the value of the function at x=0

Real Coefficients: Complex roots occur in conjugate pairs | Complex Coefficients: Complex roots do not necessarily occur in conjugate pairs

Root: A solution to the polynomial equation p(x) = 0, can be real or complex | X-intercept: A point where the graph crosses the x-axis, only represents real roots

Even Degree: Ends go in the same direction (both up or both down) | Odd Degree: Ends go in opposite directions (one up, one down)

Linear: Degree 1, graph is a straight line | Quadratic: Degree 2, graph is a parabola

Rational: Can be expressed as a fraction p/q where p and q are integers | Irrational: Cannot be expressed as a fraction, decimal representation is non-repeating and non-terminating

Multiplicity 1: The graph crosses the x-axis | Multiplicity 2: The graph touches the x-axis and turns around.

x=a is a zero with even multiplicity. The function's sign does not change at x=a.

x=a is a zero with odd multiplicity. The function's sign changes at x=a.

The degree is related to the number of turning points (local maxima and minima). A polynomial of degree n can have at most n-1 turning points. Also, consider the end behavior.

Real zeros are the x-intercepts of the graph.

The end behavior indicates the sign of the leading coefficient and whether the degree is even or odd.

Symmetric about the y-axis.

Rotationally symmetric about the origin.

It suggests a zero with a higher multiplicity or a turning point.

Look at whether the graph is above (positive) or below (negative) the x-axis in each interval.

The value of the polynomial when x = 0, i.e., p(0).
