Question

Matt collects classic stamps. For his birthday this year, his grandma gave him a stamp worth $40. He expects the stamp's value to double every decade. Assuming Matt is right, you can use a function to approximate the stamp's value x decades from now. Write an equation for the function.

Answer 1

Explanation:

If the stamp's value doubles every decade, then the value of the stamp after x decades will be $40 multiplied by 2 raised to the power of x.

Therefore, the equation for the function that approximates the stamp's value x decades from now is:

V(x) = $40 x 2^x

Where V(x) represents the stamp's value x decades from now.
