The Cubing Function

Question 13 • (OC27) MATH COLL ALGEBRA-1200710-S1-Degele-VOL7006P

Graph the function y=x3+6x2+2x-11. Based on the graph, what is the largest possible x-value if y=0? Round your answer to the nearest hundredth, if necessary.

Answer
A
1.11
B
1.9
C
5.2
D
13.2

Explanation

Set y equal to 0 and solve x³ + 6x² + 2x − 11 = 0. The graph crosses the x-axis at approximately x = 1.11; for example, the function is slightly negative at x = 1.1 and slightly positive at x = 1.11. Thus the largest x-value is 1.11, choice A.
