Answer:
5 and 13
Step-by-step explanation:
To evaluate (w ￮ u)(8) , evaluate u(8) then substitute the value obtained into w(x) , that is
u(8) = = 8 + 9 = 17 , then
w(17) = =
= 5
---------------------------------------
To evaluate (u ￮ w )(8) , evaluate w(8) then substitute the value obtained into u(x) , that is
w(8) = =
= 4 , then
u(4) = 4 + 9 = 13
