Given the function f(x)=3x-1, find f(x+2)

astra-53 [7]

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
