Answer:
Explanation:
To answer the questions regarding the function f(x), let's go step by step:
20. To find f(7), we need to substitute 7 into the function. However, the function f(x) is not given, so we cannot determine the value of f(7) without knowing the function.
21. Similarly, to find f(-6), we need the function f(x) to substitute -6 into it. Since the function is not provided, we cannot determine the value of f(-6).
22. Again, without the function f(x), we cannot find the value of f(3).
23. To list the x-values that make f(x) = -2 true, we need to know the function f(x) and find the values of x that satisfy f(x) = -2. Without the function, we cannot list the x-values.
24. Similarly, to list the x-values that make f(x) = -5 true, we need the function f(x). Without the function, we cannot provide the x-values.
25. Without knowing the function, we cannot determine if it is a function or not. In order for it to be considered a function, each input (x-value) must have a unique output (y-value).
26. The domain of a function refers to the set of all possible x-values for which the function is defined. Since the function f(x) is not given, we cannot determine its domain.
27. The range of a function refers to the set of all possible y-values or outputs of the function. Without knowing the function, we cannot determine its range.
In summary, without the specific function f(x) provided, we cannot answer the questions regarding its values, domain, range, or whether it is a function or not.
