f(x)=10(1.25)xThe function models f, the price of a rare trading card in dollars x years after its initial release in 1993. Based on the model, what is the price of the trading card 20 years after its initial release?
Q. f(x)=10(1.25)xThe function models f, the price of a rare trading card in dollars x years after its initial release in 1993. Based on the model, what is the price of the trading card 20 years after its initial release?
Identify Function & Value: Identify the function and the value of x to substitute. The function given is f(x)=10(1.25)x, and we need to find the price 20 years after 1993, so x=20.
Substitute x=20: Substitute x=20 into the function to find f(20). Calculate f(20)=10(1.25)20.
Compute (1.25)20: Use a calculator to compute (1.25)20. The result is approximately 86.7378.
Multiply by 10: Multiply the result by 10 to get the final price. f(20)=10×86.7378=867.378.
