$260

I don’t know what model/formula you are supposed to be using.

But what I did first was calculated what 30% of 2700$ is.
2700 x .3 = 810

So it depreciates $810 per year.

$810 x. 3 years = 2430

2700 - 2430 = 260

In three years, the laptop will be worth $260

Explanation:

f(x) = (x-4)(x+2)

1) For x-intercept, y will be 0

(x-4)(x+2) = 0

(x-4) =0, (x+2) = 0

x = 4, x = -2

x-intercept: (4, 0), (-2, 0)

2) For vertex: x = -b/2a where ax² + bx + c

Quadratic function:

(x-4)(x+2)

x² +2x-4x -8

x² -2x -8

vertex:

x = -(-2)/2(1)

x = 1

y: (x-4)(x+2) = (1-4)(1+2) = -9

ordered pair of vertex: (1, -9)

3) For y-intercept, x will be 0

(x-4)(x+2)

(0-4)(0+2)

-8

y-intercept: (0, -8)
