Concept explainers
To find : all the zeros of the function
Answer to Problem 92E
The zeros of the function are:
Explanation of Solution
Given information:
Concept Involved:
Synthetic Division (for a Cubic Polynomial):To divide
In case when we have a polynomial with a missing term, insert placeholders with zero coefficients for missing powers of the variable. Vertical pattern: Add terms in columns Diagonal pattern: Multiply results by k. This algorithm for synthetic division works only for divisors of the form x - k. Remember that |
The Division Algorithm: If
…where
If theremainder
Graph:
Interpretation:
The point where the graph of the function cuts the x-axis are called zeros of the polynomial. From the above graph we see at
