Question 9 • CR - Algebra 2 26-27 - S1
Because the function is continuous, a change from positive to negative values or vice versa indicates at least one zero between those x-values. The table shows sign changes between −2.4 and −1.8, −1.8 and −1.2, 1.2 and 1.8, and 1.8 and 2.4. It also gives y = 0 at x = 0, for 5 zeros total. The correct choice is 5.
