What is the Rule for a function table with the following information.
A child's admission is $4 more than half an adults admission. Input (x) as follows: 20, 26, 30, and 42.
Thanks

x = Adult admission,
x/2 + 4 = childs' admission.
Y = F(x) = x + x/2 + 4,
Y = F(x) = 3x/2 + 4,
F(20) = 3*20/2 + 4 = 34,
F(26) = 3*26/2 + 4 = 39,
F(30) =
F(42) =
(x , y)
(20 , 34)
(26 , 39)
You may finish the procedure.
