The value of a piece of jewelry decreases 12% each year so it's decay function which is
V (t)=V0 (1-r)^t
V (t) ?
V0 2200
R 0.12
T 7 years

V (7)=2,200×(1−0.12)^(7)
V (7)=2,200×(0.88)^(7)
V (t)=899.09

Answer:

 f(x) = -1/2x +1

Step-by-step explanation:

The line crosses the y-axis at y=1, so the y-intercept is b=1.

The line drops 1 unit for a run of 2 to the right, so the slope is ...

  m = rise/run = -1/2

The slope-intercept form of the equation of the line is ...

  y = mx + b

  y = -1/2x + 1

In functional form, the equation is ...

  f(x) = -1/2x +1
