Answer:

graph representing the function f of x equals 30 multiplied by 0.88 raised to the exponent of x

Step-by-step explanation:

The deodorant starts to evaporate, indicating a mass reduction, thus 12% represents the decay rate. In exponential decay, the function's graphical representation adheres to the formula:

$y=a(1-r)^x$

Where $a$ signifies the starting quantity ( $a=30$ ), $r$ is the decay rate ( $r=0.12$ ) and $x$ denotes the time intervals, measured in days for this case. By inserting the given values into the formula:

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

Which aligns with the "graph representing the function f of x equals 30 multiplied by 0.88 raised to the exponent of x".
