For zeroes/roots r1,r2, r3
the facors of the polynomial is
(x-r1)(x-r2)(x-r3)
roots
-3,2,5
(x-(-3))(x-2)(x-5)
(x+3)(x-2)(x-5)
the coefient of the x term is -4
so mutliply the whole thing by 2
(2)(x+3)(x-2)(x-5)
expand
f(x)=2x^3-8x^2-22x+60
Step-by-step explanation:
[70,30] = 210 miles per hour
Answer:
The function to determine the value of your car (in dollars) in terms of the number of years t since 2012 is:

Step-by-step explanation:
Value of the car:
Constant rate of change, so the value of the car in t years after 2012 is given by:

In which f(0) is the initial value and r is the decay rate, as a decimal.
In 2012 your car was worth $10,000.
This means that
, thus:

2014 your car was worth $8,850.
2014 - 2012 = 2, so:

We use this to find 1 - r.






Thus
