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)
2

4

8

16

32
g(x)
2

2

2

2

2


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

2x + 2

2x + 2

2x + 2x

2(2x)

Answer 1

2^(x+2)
2^x + 2
2^x + 2x
2(2^x)

Answer 2

what are those ?

Answer 3

for x=1 , f(x)=2
for x=2 , f(x)=4
for x=3 , f(x)=6
for x=4 , f(x)=8

for all the values of x, f(x) is being equal to 2x
for g(x), for all the values of x, g(x) is being equal to 2

f(x)=2x and g(x)=2

what is f(x)+g(x)=

Answer 4

so it would be 2x + 2? so B?

Answer 5

correct

Answer 6

ok thanks again :D

Answer 7

any time :)
