Questions: Question 10 The graph of a function f is given. Use the graph to answer the question. For what numbers x is f(x)<0 ? (-60,70) (-∞,-60) (-60, ∞) [-100,-60),(70,100)

Solution Steps

Examine the graph to determine where the function \( f(x) \) is less than 0. This occurs where the graph is below the x-axis.

From the graph, identify the x-values where the function crosses the x-axis and the intervals where \( f(x) \) is negative. The function is below the x-axis in the intervals:

• From \( x \approx -100 \) to \( x \approx -60 \)
• From \( x \approx 0 \) to \( x \approx 70 \)

Compare the identified intervals with the provided answer choices:

• \((-60, 70)\)
• \((-\infty, -60)\)
• \((-60, \infty)\)
• \((-100, -60), (0, 70)\)

The correct intervals are \((-100, -60)\) and \((0, 70)\).
