I have done things like that and I think it is B

Step-by-step explanation:

That is the answer I believe.

For finding the values, we look at the x - value given. Then we move to where it is on the graph and find its y  value.

In part A, when x = -4, the y value looks to be between -3 and -4. Let's put it in the middle and estimate it at -3.5

In part B, when x = 1, the process is similar.  Go to x = 1, then go to the graph, then go to the y value.  That looks to be at y = -3.

In part C, when x = 4, there are three values that work. We are actually answering part D at this point because we can tell this graph is NOT a function of x. When you have an x -value that goes into the function, you have to get EXACTLY ONE thing that comes out.  I bolded "EXACTLY ONE" because those words make the definition work. Two or more, not a function. One, it's a function. None, and it's not in the domain at all.  There are three values of y that work, and they are - from top down, 3.5, 0, -2.5.

We answered Part D when observing part C. It's NOT a function because there is not EXACTLY ONE value of y for an x.

And finally, because it's not a function - finding the domain and range is a waste of time. You can't find the domain of something that's not a function - you need a function to have a domain.

Hope that helps.

Step-by-step explanation:

The range of a function in this form is always f(x)≤k, where k is the y-intercept and f(x) is the range.

$f(x) = 4(3)^x$

Step-by-step explanation:

Let the function that shows the given situation is,

$f(x) = a(b)^x$

Where x is the number of years.

Initially,  x = 0,

$f(0) = a(b)^0 = a$

According to question f(0) = 4

Thus, a = 4

Since, each year the number of fish is increased by 3 times,

That is, for x = 1, f(1) = 12

But, $f(1) = a(b)^1$

⇒ $12 = 4(b)^1$

⇒ b = 3

By putting the values of a and b in the above function,

We get, $f(x) = 4(3)^x$

Which is the required function that shows the given situation.

⇒ Option D is correct.

Mean:It is the average

range: it is the set of outputs the function achieves

hope this. Helps 🙂

Greetings! Hope this helps!

D {-3, 5}

R: {0,4}

Have a good day!

A brainliest would help tons! 😀
