Question

hey guys ans plzz....



what is the period of
$f(x + 4) + f(x + 4) = f(x)$
?

Answer 1

f(x)=3x+2f(x)=3x+2, what is the value of f(3)f(3)? Just plug 33 for xx, f(3)=3∗3+2=11f(3)=3∗3+2=11, so if the function is f(x)=3x+2f(x)=3x+2, then f(3)=11f(3)=11.

Answer 2

f (x + 4) +f(x +4) = f (x)

put x + 4 ag the place of x

f (x + 8) + f (x +8) = f (x +4)

Hence its Periodicity would be 4.
