Step-by-Step Solution

The problem is asking us to identify for which x x values f(x)>0 f(x) > 0 based on the graph provided, which seems to depict a quadratic function. Let's go step-by-step:

First, we need to determine the points where the function intersects the x-axis, which are the roots of the function. The graph shows these intersections at x=2 x = -2 and x=2 x = 2 . These are the points where the function is equal to zero, f(x)=0 f(x) = 0 .

Next, we observe the overall shape of the graph to understand where f(x)>0 f(x) > 0 (i.e., where the graph is above the x-axis). Typically for a quadratic function, which is a parabola, the parabola will be above the x-axis outside the roots if it opens upwards, and between the roots if it opens downwards, given that a(xx1)(xx2)=0 a(x - x_1)(x - x_2) = 0 with root analysis on a>0 a > 0 .

In the provided graph, the parabola appears to open upwards. Therefore, the function f(x) f(x) is positive when x x is less than the smaller root, 2 -2 , or greater than the larger root, 2 2 . This is a typical behavior for a quadratic function which opens upwards, where it takes negative values inside the range of its roots and positive values outside.

Conclusively, f(x)>0 f(x) > 0 for the intervals where x<2 x < -2 or x>2 x > 2 .

Therefore, the solution to the problem is x>2 x > 2 or x<2 x < -2 .

Answer

x > 2 or x < -2
