Answer:
A. 12 only.
Step-by-step explanation:
We have been given a graph of a function. We are asked to find the value of [tex]f(0)[/tex].
The [tex]f(0)[/tex] will be the point, where our given graph crosses y-axis.
Upon looking at our given graph, we can see that our graph crosses y-axis at [tex](0,12)[/tex].
Therefore, [tex]f(0)=12[/tex] and option A is the correct choice.
