belka [17]

Answer:

graph of function f of x equals 30 multiplied by 0.88 to the power of x

Step-by-step explanation:

The deodorant is begun to evaporate in other words, it is losing mass so the rate of 12% is a decay rate.  In the exponential decay, the graph of the function goes according to the formula:

y=a(1-r)^x

Where a is the initial amount (a=30), r is the rate of decay (r=0.12) and x the times intervals, in this case, measured in days. Substituting the values in the formula:

y=30(1-0.12)^x\\y=30(0.88)^x

Which corresponds with the "graph of function f of x equals 30 multiplied by 0.88 to the power of x".
