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

4(v+7) = -6(3v-4) +8v<br>​
xxTIMURxx [149]

Answer:

v=−27

Step-by-step explanation:

Since v is on the right side of the equation, switch the sides so it is on the left side of the equation.

−6(3v−4)+8v=4(v+7)

Simplify −6(3v−4)+8v

−10v+24=4(v+7)

Simplify 4(v+7).

−10v+24=4v+28

Move all terms containing v to the left side of the equation.

−14v+24=28

Move all terms not containing v to the right side of the equation.

−14v=4

Divide each term by −14 and simplify.

v=−27

The result can be shown in multiple forms.

Exact Form:

v=−27

There are 6060 tables in a restaurant, with 25%25% of them seating 22 people. The tables remaining seat 44 people. How many seat
mestny [16]
60 tables total. 25% of those seat 22 people. 60 X 25% = 15. So 15 of the tables seat 22 people. 
The remaining tables (60 tables - 15 tables = 45 tables) seat 44 people. 

So you have:
(15 tables X 22 seats) + (45 tables X 44 seats) = total seats. 
2310 TOTAL seats.
