Question

In a function, each input value (x) corresponds to one output value (y). Complete each function table
Rule: Y= -x/2 + 4
X. Y
-4 _______
-2 _______
0 _______
8. _______
11 _______

Answer 1

Using the rule Y = -x/2 + 4:

For x = -4:
Y = -(-4)/2 + 4
Y = 2 + 4
Y = 6

For x = -2:
Y = -(-2)/2 + 4
Y = 1 + 4
Y = 5

For x = 0:
Y = -0/2 + 4
Y = 4

For x = 8:
Y = -8/2 + 4
Y = -4 + 4
Y = 0

For x = 11:
Y = -11/2 + 4
Y = -5.5 + 4
Y = -1.5
