  • C. 8

Explanation:

B

Difficulty: Medium

Strategic Advice: The maximum of a function is the point at which the range (the y-values) of the function is at its highest. Identify that point on the graph, and then determine the corresponding x-value. Pay careful attention to the axis labels-they are not given in increments of 1.

Getting to the Answer: The maximum value of h(x) (the highest point h reaches on the graph) is 8. Drop down from the maximum to the x-axis to find that the corresponding x-value is 6, which matches (B).
