Final answer:
The initial value of the exponential function represented by the table is -2.
Step-by-step explanation:
The initial value of an exponential function can be determined by looking at the table.
The initial value is the value of the function when the input (x) is equal to 0. In the given table, you can see that when x=0, the function has a value of -2.
Therefore, the initial value of the exponential function represented by the table is -2.
