What are the domain and range of f(x) = 2(3X)?

<h3>Answer: Choice A</h3>

Domain: (-\infty,\infty)

Range: (0,\infty)

==============================================================

Explanation:

I'm assuming the function is f(x) = 2(3)^x which is an exponential function.

The domain of any exponential function is the set of real numbers. In interval notation, the domain is (-\infty, \infty) which says we can pick any number between negative infinity and positive infinity: aka any number we want. There are no restrictions to worry about such as division by zero errors.

The range of this exponential function is the set of y values such that y > 0. It often helps to see the graph of what is going on (see below). Note how as x heads to the left, and gets more negative, the curve approaches the x axis. It never actually touches it however. So it will never reach y = 0 itself but instead just get very close. The inequality y > 0 translates to the interval notation (0,\infty)

----------

Summary:

Domain: (-\infty,\infty);  Range: (0,\infty)

So that's why the answer is choice A

It's simple.  First, multiply 3/4 by 5.  As a decimal, this equals 3.75.  Therefore, the number of miles marine bikes on Tuesday is between 3 and 4.

Hope I helped! :)
