Hi, here is my answer:
First, if you want to determine that's relation is function, you have to realize that your value of x(Domain) is not repeated.= so, it's a function
But...If your value of x (Domain) is repeated twice or more, so I can guaranteed that is totally NOT a function

Hi there! To answer your question or more questions like these you'd want to determine that relation is function, the value of x which would be your base or domain is not repeated, so by using this guideline you can determine if it's a function. On the other hand, if your value of x is repeated twice or more (+), it isn't a function. Hope this helps you and remember to mark as brainliest! BTW I like the question. It made me think a lot. :)

Considering the function for the remaining amount of cesium in the atmosphere, F(x) = 1000×0.5^(x/30), we have;

First part:

  • The area will be safe again in about 100 years time.

Second part;

  • The y-intercept is at the start of the measurement

Third part;

  • The function is a decay function

<h3>Which method can be used to evaluate the given function?</h3>

First part;

The given function for the remaining amount of cesium is presented as follows;

F(x) = 1000 \times  {0.5}^{ \frac{x}{30} }

When 100 kg. of cesium is remaining, we have;

100= 1000 \times  {0.5}^{ \frac{x}{30} }

Which gives;

\frac{x}{30}  =  \frac{ log(0.1) }{ log(0.5) }

x=  \frac{ log(0.1) }{ log(0.5) }  \times 30 \approx  100

  • Therefore, the area will be safe again in approximately 100 years.

Second part;

The y-intercept is given by the point where <em>x </em>= 0

At the y-intercept, we therefore have;

F(0) = 1000 \times  {0.5}^{ \frac{0}{30} }

  • F(0) = 1000

At the y-intercept, the amount of cesium remaining, F(x) is 1,000, which is the initial amount of cesium.

  • The y-intercept is therefore, at the start of the measurement, where 1000 kg. is present in the atmosphere.

Third part;

The amount of cesium remaining F (x) decreases as the time, <em>x</em>, increases, the function is therefore a decay function.
