Question

The following table shows the values of f(x) and g(x) for different values of x:



x
1

2

3

4

5

f(x)
3

9

27

81

243

g(x)
4

4

4

4

4



Which of the following best describes the function f(x) + g(x)?

3x + 4

3x + 4

3x + 4x

4(3x)

Answer 1

can you please write the tables normally ?

Answer 2

yeah sorry

x 1 2 3 4 5
f(x) 3 9 27 81 243
g(x) 4 4 4 4 4

Answer 5

The first two options look exactly the same

Answer 6

I'm sure one is supposed to be different, please recheck them

Answer 7

All the same, I can help you with this question if you still need it

Answer 8

The answer is, 3x+4. I'll explain each section to you.

3x,
It asks for f(x)+g(x). The f(x) begins with 3, and if a number is put in, it'll increase as you see on the table.

+4,
Each value on the g(x) is 4, so there won't be any x afterwards because it's not increasing.

Answer 9

oh sorry i have to right them on the equation thing
\[3^x +4\]
then 3^X^+4 (couldent figure out how to do it on the equation thing)
\[3^x+4x\]
\[4(3^x)\]

those are the choices @kohai

Answer 10

It'll be the first one, in that case.
Take a look,

3^1=3
3^2=3*3=9
3^3=3*3*3=27

That follows the table correctly. As far as the g(x) goes, it's 4 for each value so there won't be an x.

Also, it asks for f(x)+g(x), so you can scratch a few answer choices off that way

Answer 11

lol thanks do you think you can help me with a few more im not going to give you like 20 more like other people do just 4

Answer 12

Close this question and then post a new one, I'll take a look at it. If I can help you I will, if not it'll give other people an opportunity to look at it
