= 4(x-3)² -36+20
</span>f(x) = 4(x-3)² -16 (vertex form)
Answer: She is incorrect because 0 + 0 = <u>0</u>
13 + (-12) - (-5)
13 - 12 + 5

Step-by-step explanation:
Answer:
A) f(t) = 29,800(0.89)^t
Step-by-step explanation:The truck value decreases by 11% each year.
The present value of the truck was $29,800.
29,800 x 0.11 = 3,728 dollars lost from value.
29,800 - 3,728 = 26,522, the value of the truck after one year.
26,522 x 0.11 = 2,917.42 cash lost from value.
26,522 - 3,728 = 23,604.58, the value of the truck after two years.
Therefore, the answer is A) f(t) = 29,800(0.89)^t.
