Answer:
4
Step-by-step explanation:
if we see the table as being a numerical representation of a graph in the x-y plane, the first column will represent the x-values (i.e the domain) and the second column will represent the y-values (i.e the range).
That is to say, the x-values are the inputs into the function that will spit out the y-values as outputs.
By observation, we can see that when x = 0 (i.e the initial value of the input), that the resulting function output is y =4 (i.e the initial value of the output).
Hence the initial value of the function (i.e the output) is 4
