Step-by-step explanation:
The slopes of perpindicular lines must be negative reciprocals of each other -- while -4 and 4 are negative to each other, the negative recipricocal for -4 is 1/4 and -1/4 for 4.
The slopes of parallel lines must be the same, so these are not parallel.
F(a+2) = 3(a+2)+5/(a+2)
f(a+2) = 3a+6 + 5/(a+2)
