Question

the graph of y = f(x) is given below. (click on a graph to enlarge it.) at which of the marked x - values can the following statements be true? enter x1 for the i^th marked x - value; for example, x1 for the first marked x - value. to enter multiple values, enter the x - values in a comma - separated list. enter dne if no such x - value exists. a. f(x)>0

Explanation:

Step1: Analyze graph for positive - y values

The function \(y = f(x)\) is positive when its graph is above the \(x\) - axis.

Step2: Identify marked \(x\) - values

By observing the graph, we see that the graph of \(y = f(x)\) is above the \(x\) - axis at \(x_1\), \(x_4\) and \(x_5\).

Answer:

x1,x4,x5
