Answer:
Option D.
Step-by-step explanation:
If the graph of a function f(x) passes through the point (a,b), then the value of the function f(x) is b at x=a.
[tex]f(a)=b[/tex]
[tex]y=b[/tex]
The graph of a function is given.
We need to find the value of function at x=-2.
From the given graph it is clear that the graph is passes through the point (-2,3).
It means the value of function is 3 at x=-2.
[tex]y=3[/tex]
Therefore, the correct option is D.
