Question: Shelby invests $3,000 in a bank account that earns 6% in interest, compounded annually. Thus, the amount of money she has in her account
Shelby invests $3,000 in a bank account that earns 6% in interest, compounded annually. Thus, the amount of money she has in her account is modeled by M(x) = 3000(1.06), where x is the number of years the account has been open. A) Sketch a graph of this function in an appropriate window. Only go up to x = 20. B) How do you know this function is invertible? C) What are the units of the input and output of the inverse function, M-? D) Using the graph of the original function, estimate the value of M-(6000). Round your answer to the nearest whole number. Explain what this value means in a sentence. [Do not use logarithms - just use the graph]
