For the Polynomial, List Each Real Zero and Its Multiplicity

question 21

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)0, multiplicity 2, touches x-axis; 1, multiplicity 1, crosses x-axis; multiplicity 1, crosses x-axis; multiplicity 1, crosses x-axis
• B)0, multiplicity 2, crosses x-axis; 1, multiplicity 1, touches x-axis; multiplicity 1, touches x-axis; - multiplicity 1, touches x-axis
• C)0, multiplicity 2, touches x-axis; 1, multiplicity 1, crosses x-axis
• D)0, multiplicity 2, crosses x-axis; 1, multiplicity 1, touches x-axis

Heuristic

A simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms.

Heuristics

Mental shortcuts or rules of thumb that simplify decision making, often used in problem-solving and judgment situations.

Algorithms

Step-by-step procedures or formulas for solving problems or completing tasks, often used in mathematics and computer science.
