(a)
To calculate: The zeros of polynomial.
(a)

Answer to Problem 37CR
The intervals are: (-3,-2), (-1, 0) and (3, 4)
Explanation of Solution
Given information:
Calculation:
Intermediate value theorem states that if a continuous function takes two values say
By this theorem we can say that if at one point the function is having a positive value and at other point it is having a negative value then between those intervals have a zero of the polynomial.
The table for the polynomial
x | F(x) |
-3 | - |
-2 | + |
-1 | + |
0 | - |
1 | - |
2 | - |
3 | - |
4 | + |
The intervals are (-3,-2), (-1, 0) and (3, 4)
(b)
To calculate: zeros of the polynomial to nearest thousand.
(b)

Answer to Problem 37CR
The zeros of polynomial are: -2.979, -0.554 and 3.533
Explanation of Solution
Given information:
The interval are (-3,-2)(-1,0) and (3,4)
Calculation:
a) Adjusting the interval by 0.1 ,0.01 ,0.001 and 0.0001
x | F(x) |
-2.9 | - |
-3.0 | + |
x | F(x) |
-2.97 | - |
-2.98 | + |
x | f(x) |
-2.979 | - |
-2.980 | + |
So one zero of polynomial is -2.979
Similarly for the interval (-1, 0) and (3, 4) the other two zeros are -0.554 and 3.533
