End behavior:
b.
The changes in sign indicate that there are zeros between x = 1 and x = 2 and between x = 2 and x = 3. So, there are
two zeros.
c .
d.
Sample answer: Sometimes it is necessary to have a more accurate viewing window or to change the interval values
of the table function in order to assess the graph more accurately.
48. REASONING The table below shows the values of g(x), a cubic function. Could there be a zero between x = 2 and
x = 3? Explain your reasoning.
