Question

1). Which of the following best describes the function y = 86(1.014)x ?

Anything Goes Function
Exponential Decay Function
Exponential Growth Function
None of these

2).Is y = 86(0.74)x an exponential growth function or an exponential decay function?

3). The value of Mr. Cox’s car x years after its purchase is given by the function, V(x) = 20,000(0.85)x. Approximately, what was the value of Mr. Cox’s car 5 years after its purchase? Round to the nearest dollar.

Answer 1

1. wats a anything goes function
it is exponential grouth because
in y=ab^c, if b>1 then it is grouth

growth is answer



2. decay since 0<b<1

3. 5 years so
V(5)=20000(0.85)^5
V(5)=8874.11
round
$8874
