Step-by-step explanation:
we know that
The exponential function while the player is still active is equal to
where
y ----> is the value of the baseball card
x ----> the time in years
Find the value of y for x=7 years (7 years still active)
After 20 years
x=20-7=13 years (13 years retired player)
The initial value is
The new equation is equal to
substitute
x=13 years
