Answer to Problem 30PPS
Between −6 and−5 and −4 and−3 .
Explanation of Solution
Given:
The given table is:
x | −7 | −6 | −5 | −4 | −3 | −2 | −1 | 0 |
f(x) | −8 | −1 | 4 | 4 | −1 | −8 | −22 | −48 |
Calculation:
Based on the table shown, the x -intercept indicate that one solution is between −6 and−5 there must be a zero since we go from negative to positive. Similarly, there must be a zero between −4 and−3 since we move from positive to negative.
Hence, the solution of the given equation is between −6 and−5 and −4 and−3 .
