Answer: The domain of f(x) is the set of all possible values of x that make the function defined. The range of f(x) is the set of all possible values of y that the function can take. To find the domain and range of f(x), we can look at the graph and see where the function starts and ends.
The domain of f(x) is [-9, 9], because the graph starts at x = -9 and ends at x = 9. The range of f(x) is [-3, 3], because the graph reaches its lowest point at y = -3 and its highest point at y = 3.
The domain and range of this function are different from the other functions you have seen in this topic because they are finite. Most of the functions you have seen in this topic have infinite domains and ranges, meaning that they can take any value of x or y. For example, the function y = x^2 has an infinite domain and range, because it can take any value of x and produce any positive value of y. However, the function f(x) has a finite domain and range, because it can only take certain values of x and produce certain values of y. This is because f(x) is a piecewise linear function, which means that it is made up of different linear segments that have different slopes and intercepts.
