The function k(x) is defined in this table: X 0 1 2 3 4 k(x) 2 3 6 11 18 And the function m(x) is defined by this graph: yEm ( x ) 4 -4 -2 2 14 8 10 12 +2+ a. Find k(0) if possible. If it is not possible to find, write DNE and explain why. b. Find k-1(0) if possible. If it is not possible to find, write DNE and explain why. c. Write a domain restriction for m(x) that would result in the inverse of the graph being a function
