The function g(x) represents f(x) = 9 cosine (x minus startfraction pi over 2 endfraction) + 3 after translating startfraction pi over 6 endfraction units left and 4 units up. Which equation represents g(x)? g (x) = 9 cosine (x minus startfraction pi over 3 endfraction) minus 1 g (x) = 9 cosine (x minus startfraction pi over 3 endfraction) + 7 g (x) = 9 cosine (x minus startfraction 2 pi over 3 endfraction) minus 1 g (x) = 9 cosine (x minus startfraction 2 pi over 3 endfraction) + 7.
