The problem is asking us to identify for which values 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 and . These are the points where the function is equal to zero, .
Next, we observe the overall shape of the graph to understand where (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 with root analysis on .
In the provided graph, the parabola appears to open upwards. Therefore, the function is positive when is less than the smaller root, , or greater than the larger root, . 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, for the intervals where or .
Therefore, the solution to the problem is or .
x > 2 or x < -2
