Answer:
f(-2)=3
Step-by-step explanation:
we know that
f(-2) means the value of the function when the value of x is equal to -2
Remember that
the closed circle at x=-2 include the value of x=-2
the open circle at x=-2 not include the value of x=-2
Looking at the graph
For x=-2 (closed circle) the value of y is equal to 3
therefore
f(-2)=3
