For the Polynomial, List Each Real Zero and Its Multiplicity

question 23

Multiple Choice

For the polynomial, list each real zero and its multiplicity. Determine whether the graph crosses or touches the
x-axis at each x -intercept.
-

• A)-4, multiplicity 1, crosses x-axis; 4, multiplicity 2, touches x-axis
• B)4, multiplicity 1, crosses x-axis; -4, multiplicity 2, touches x-axis
• C)-4, multiplicity 1, touches x-axis; 4, multiplicity 2, crosses x-axis
• D)4, multiplicity 1, touches x-axis; -4, multiplicity 2, crosses x-axis

Definitions:

Indicator Variables

Dummy variables used in regression models to encode categorical data into numbers, typically 0 or 1, to include them in statistical analysis.

Number of Hours

The total count of hours measured in a given context, often referring to the duration of events or the amount of time spent on activities.

Nominal Variable

A type of variable that represents categories with no intrinsic ordering or rank among them.

Indicator Variables

Binary variables used in regression analysis, taking the value of either 0 or 1 to denote the absence or presence of a categorical effect.
