Answer:

Step-by-step explanation:

This is an exponential function. These types of functions have asymtotes. Asymtotes are when x or y is approaching a specific value, but it's not touching it. If you put your function in a graphing calculator, you will find that the y is approaching 0, but it's not quite touching it. What we're looking for, however is domain (x), and there are no asymtotes for x because as you can see, every value on the x axis has a y point. Therefore the domain is all real numbers.

Answer: B. All real numbers

<u>Step-by-step explanation:</u>

f(x) = 3ˣ

There is NO restriction on x .

x can be positive, negative, fractions, square roots, etc.

--> x is All Real Numbers.

Note: There IS a restriction on f(x) --> f(x) > 0

Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.

Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.

So, X intercept - (2,0)
Y intercept - (0,3).

Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.

Now put everything together in form:

Y = mx + b

Y = -3/2x + 3.

I believe this is the solution.
