The graph below represents functions ƒ(x) and g(x).

which value(s) of x makes ƒ(x) = g(x) a true statement?

0
1
2
3

For this case we have the following functions:
 g (x) = 3 ^ x + 1
 f (x) = 3x + 1
 We observe that the graph of both functions are cut in the value of:
 x = 1
 Therefore, the value of the functions is the same for that value of x.
 Let's check it: g (1) = 3 ^ 1 + 1 = 3 + 1 = 4
 f (1) = 3 (1) + 1 = 3 + 1 = 4
 
 ƒ (x) = g (x) is a true statement for:
 x = 1
