Answer:

The function rule is:

[tex]y=-\frac{1}{2} x-1[/tex]

Step-by-step explanation:

We identify the output with the variable "y", the "input with the variable"x". Notice also that the "opposite of the input is "-x" (negative x), and therefore the words "the output is one less than half of the opposite of the input" translate into:

[tex]y=\frac{1}{2} (-x)-1\\y=-\frac{1}{2} x-1[/tex]
