Answer:
Option A
Step-by-step explanation:
The given function is a linear function therefore rate of change of this function will be the slope of the given line.
Since this line passes through two points ( 0,1 ) and ( 0.5 0 )
the slope of the line = [tex]\frac{(y-y')}{(x-x')}[/tex]
slope = [tex]\frac{(1-0)}{(0-0.5)}[/tex]
= ( -2 )
Therfore, Option A will be the answer.
