What is the y-intercept for the polynomial given by y = (x - 3)(x - 4)?

Back

(0, 12)

Front

Define a polynomial function.

Back

A polynomial function is a function that can be expressed in the form P(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 a zero of a polynomial?

Back

A zero of a polynomial is a value of x for which P(x) = 0.

Front

Explain the relationship between the degree of a polynomial and the number of zeros.

Back

The degree of a polynomial function indicates the maximum number of zeros it can have.

Front

What is the y-intercept of a polynomial function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, found by evaluating the function at x = 0.

Front

How do you find the zeros of a polynomial function?

Back

To find the zeros, set the polynomial equal to zero and solve for x.
