Question

When Bazillium released its signature trading-card game, Wandering Wizards, the value of a first-edition deck decreased at first. As the game got more popular and the deck became more rare, its value started to increase. The value of a first-edition deck in dollars can be modeled by the expression 0.25t2–4t+28, where t is the time in years after it was first released.

Answer 1

Yes, that is correct. The expression 0.25t2–4t+28 shows that the value of a first-edition deck of Wandering Wizards will decrease initially when it is first released, then increase as the deck becomes more rare. The maximum value of the deck is 28, which is when t=0 (when the game is first released).
