If f(x + 1) = 3x + 2, the function f could be defined by which of the following?
A) f(x) = 3x - 2
B) f(x) = 3x - 1
C) f(x) = 3x +1
D) f(x) = 3x + 5

c) F(x)= 3x+1

Explanation:

Here, f(x+1) = 3x+2

or, f(x+1-1) =3x+2-1

or, f(x) = 3x + 1

the answer is f(x) = 3x+5

Explanation:

f(x-1) = 3x + 2

Let, x-1 = a

or, x = a + 1

or, f[a+1-1] = 3(a+1) +2

or, f(a) = 3a + 5

or, f(x) = 3x + 5

not b. i am not sure what it is but not b
