Best ResponseYou've already chosen the best response.0okay sure... so f(x) = –2 cos 4x – 3 when you plug in 0, you have 2 cos(4(0)) 3 which is equal to 2 cos(0) 3 = 2(1)3 =23 =5

Best ResponseYou've already chosen the best response.0when you plug in π/4, you get 2(cos4(π/4))3 so you get 2 cos(π) 3 =2(1)3 =1
