Question

EDIT: This is actually for Middle School mathematics, I apologize.
I don't want the answer straight away, please. Could some one work me through this problem? I'm kind of confused on it. Any help is much appreciated.
The tables below show the values of f(x) and g(x) for different values of x:

f(x) = 2(3)x

x f(x)
−2 0.22
−1 0.67
0 2
1 6
2 18


g(x) = 3x + 1
x g(x)
−2 1.11
−1 1.33
0 2
1 4
2 10


Based on the tables, what is the solution to the equation 2(3)x = 3x + 1?
x = −1
x = 0
x = 1
x = 2

Answer 1

I am going to assume it is 2(3)^x since that matches the values in the table. As for finding the answer, take a close look at both tables and see which x and y value from both have the same answer. 

Answer 2

Answer: the answer is x= -33 answer b
