Question

You bought a computer for $900 in 2020. Three years later, it’s value is $460.80. Which exponential function represents the computers value, V (t), t years after you bought it?

• V(t)=900(9.65)^t
• V(t)= 900(0.8) ^t
• V(t)= 900(0.2) ^t
• V (t) = 900 (1.8) ^t

Answer 1

b

Explanation:

Answer 2

V(t)= 900(0.8) ^t

Explanation:

900
`x^(3)`=460.8

`x^(3)`=0.512

x=0.8
