Step-by-step explanation:

f(x) =  y

so f(4.999) = -5 when x = 4.999

f(5)= undefined because open circles means > or < with out the line underneath that means equal to

f(5.0001)= 7 when x=5.0001

f(9)= 7 when x=9 because the closed circle means ≥ or ≤ or equal to

Answer:

The function in the graph is:

  • f(x)= -6, when x= [-9, 2)
  • f(x)= -5, when x= [2, 5)
  • f(x)= 7, when x= (5, 9]

Therefore,

  • f(4.999)= -5,
  • f(5)= undefined,
  • f(5, 0001)= 7,
  • f(9)= 7
