Answer:
Step-by-step explanation:
Since, the function given in the graph is a piecewise function,
Piece 1 is defined in the domain → -9 ≤ x ≤ -3
Piece 2 is defined in the domain → -3 < x ≤ 4
Piece 3 defined in the domain → 4 < x < 9
x = -3.0001 is lying on piece 1,
f(-3.0001) = 3
x = 3.999 is lying on piece 2,
f(3.999) = 7
x = 4.0001 is lying on piece 3,
f(4.0001) = -3
x = 9 doesn't represent any piece,
f(9) = Undefined
