Front

What is an absolute minimum in a graph?

Back

An absolute minimum is the lowest point on a graph over its entire domain.

Front

What is the domain of a polynomial function?

Back

The domain of a polynomial function is always (-∞, +∞).

Front

What does it mean if a function has an odd degree?

Back

A function with an odd degree will have opposite end behaviors, meaning as x approaches ±∞, the function will approach ±∞.

Front

List the actual rational zeros of the polynomial function f(x) = x³ + 7x² - 2x - 14.

Back

The actual rational zeros are ±1, ±2, ±7, ±14.

Front

How do you find the y-intercept of a function?

Back

To find the y-intercept, set x = 0 and solve for y.

Front

What is a polynomial function?

Back

A polynomial function is a function that can be expressed in the form f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n, a_(n-1), ..., a_0 are constants and n is a non-negative integer.

Front

What is the leading coefficient of a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree in the polynomial.

Front

What does it mean for a function to have a positive leading coefficient?

Back

A function with a positive leading coefficient will rise to the right as x approaches +∞.

Front

What is the significance of real zeros in a polynomial function?

Back

Real zeros are the x-values where the function intersects the x-axis, indicating the values of x for which f(x) = 0.

Front

What is the difference between even and odd degree functions?

Back

Even degree functions have the same end behavior (both ends up or both ends down), while odd degree functions have opposite end behavior.
