Three years ago, andy invested $5,000 in an account that earns 5% interest compounded annually. the equation y = 5000{\left( {1.05} \right)^x} y = 5000 ( 1.05 ) x describes the balance in the account, where x is the time in years. andy has made no additional deposits and no withdrawals. how much is in the account now?

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
