Which function represents the scenario below?
B. Baseball Card
You purchased a valuable baseball card.
Every year it doubles in value.
x = years that have passed since purchase
y = value of the card
(option 1: y = 10 - 0.2x. y = 12 * (2)^x)

y = 12 * (2)^x
Part B: How much will the baseball card be worth 5 years after the purchase?
$384
$120
$22
$44
$384
$120
$22
$44
To find the value of the baseball card 5 years after the purchase, we substitute x = 5 into the function y = 12 * (2)^x:
y = 12 * (2)^5 = 12 * 32 = 384
Therefore, the baseball card will be worth $384.
y = 12 * (2)^5 = 12 * 32 = 384
Therefore, the baseball card will be worth $384.
