What is the definition of a zero of a function?

Back

A zero of a function is a value of x for which the function f(x) = 0.

Front

What does it mean for a polynomial to have an even multiplicity at a zero?

Back

It means the graph touches the x-axis at that zero but does not cross it.

Front

What is the relationship between the angles formed by a diameter and a point on the circle?

Back

The angle inscribed in a semicircle is always 90 degrees.

Front

What is the formula for the distance between two zeros of a polynomial?

Back

Distance = |x_1 - x_2|, where x_1 and x_2 are the zeros.

Front

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

Back

It determines the end behavior of the graph.
