Given:
The values in the table represent the graph of a continuous function.
To find:
The interval that must contain an x-intercept.
Solution:
From the given table it is clear that, initially y-values are negative but after negative values we get y=0.44 at x=-1.9.
This signs of y-value are different, it means the graph of continuous function must contain an x-intercept in the interval -2.3 < x < -1.9.
Therefore, the correct option is B.
