Back

-2, 7 (with multiplicity 3)

Front

What are the zeros of the function if the options are: 4, 1; -3, -1, 2, 5; -3, -1, 30, 2, 5; 3, 1, -2, -5?

Back

Front

What type of function is represented if it is described as having symmetry about the origin?

Back

Odd function

Front

If p(a) = 0 for a polynomial function p(x), what can we conclude about 'a'?

Back

a is a zero or root of p(x).

Front

What does it indicate if there is a turning point on the x-axis for a polynomial function?

Back

The multiplicity of that zero is even.

Front

Define a polynomial function.

Back

A function that is represented by a polynomial expression, which is a sum of terms consisting of a variable raised to a non-negative integer power.

Front

What is the degree of a polynomial function?

Back

The highest power of the variable in the polynomial.

Front

What is the significance of the leading coefficient in a polynomial function?

Back

It determines the end behavior of the graph of the polynomial.

Front

What does it mean for a polynomial to have a multiplicity greater than 1?

Back

The root is repeated, affecting the shape of the graph at that point.

Front

How can you determine if a polynomial function is even?

Back

If f(-x) = f(x) for all x in the domain.
