Answer: The given statement is TRUE.
Step-by-step explanation: We are given to check whether the following statement is true of false:
"f(x) is a function".
We can see from the figure that the values of x and f(x) are as follows:
x 0 3 6 9
f(x) 0 1 3 3
We know that y = f(x) is a function of x, if one value of x does not correspond to more than one value of y.
From the table, it is clear that one value of x correspond to exactly one value of f(x).
So, f(x) is a function.
Thus, the given statement is TRUE.
