Identify the initial amount a and the rate of decay r (as a percent) of the exponential function g(t) = 240(0.75)^t Evaluate the function when t= 3. Round your answer to the nearest tenth

The initial value is 240, the rate is 0.75, and the value of the function at t = 3 is 101.3

An exponential function can represent growth or decay

An exponential function is represented as:

Where:

The function is given as:

The above highlights means that:

The initial value is 240, and the rate is 0.75

Substitute 3 for t in g(t).

So, we have:

Approximate

Hence, the value of the function at t = 3 is 101.3
