Answer:
f(1) = -3
f(8) =3
f^-1 (5) =2
f^-1 (2) =4
Step-by-step explanation:
f(1) = is the value when x=1 which is -3
f(8) = is the value when x=8 which is 3
f^-1(5) is x value when y=5 so find y=5 in the table and read the x value x=2
f^-1 (2) is the x value when y=2 so find y=2 in the table and read the x value x=4
