Answer:
f(x + 2) = 3x + 5
Step-by-step explanation:
when we are given the function f(x) = 3x - 1 and asked to find f(x +2), we are basically plugging in x + 2 for x in the original function. its the input in the function
f(x + 2) = 3(x + 2) - 1 < distribute 3 into x + 2
f(x + 2) = 3x + 6 - 1 < combine like terms
f(x + 2) = 3x + 5
the solution to f(x + 2) is 3x + 5
