What cosine function represents an amplitude of 2, a period of 2n, a horizontal shift of n, and a vertical shift of -1? (6 points) f(x) = -1 cos nx + 2
f(x) = -1 cos (x - n) + 2
f(x) = 2 cos (x - n) - 1
f(x) = 2 cos nx - 1

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
