An exponential function is written as f(x) = a(b)x where a is the initial value, b is the change being made to the initial value (what the initial value is being multiplied by.)
The equation you are given is: f(x) = 29(0.6)x
Therefore the initial value (a) is 29, and the percentage of change (b) is 60% (to convert a decimal into a percent, multiple the decimal by by 100. (0.6 x 100= 60). This means the new value will be 60% of the previous value.
