Answer

Explanation:

Step1: Identify the initial - mass

The initial mass of the element is 358 grams.

Step2: Identify the rate of decay

The element is decaying at a rate of 0.6 grams per day. So, the amount of mass lost after (x) days is (0.6x) grams.

Step3: Form the function

The mass (f(x)) of the element after (x) days is the initial mass minus the mass lost. So, (f(x)=358 - 0.6x).

Answer:

A. (f(x)=358 - 0.6x)
