Answer:
f(x) = 56,000 - 2,500X
In 2026 the value will be of 20,000
Explanation:
a linear function follow the following structure:
f(x) = ax+ b
we can solve for a given two points of the formula like this:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]a = \frac{48,500 - 56,000}{2015 - 2012} = -,2500[/tex]
Now, we solve for B
48,500 = -2,500 x 3 + B
48,500 + 7,500 = B = 56,000
The formula will give 20,00 at:
20,000 = -2,500x + 56,000
36,000 / 2,500 = x = 14.4
being 2012 year 0
it will be year 2026
