Which function has the greatest y- intercept f(x) = - 9 \cos(x) f(x) = 8 \sin(x) f(x) = 7 \cos(x) f(x) = - 6 \sin(x)

Question

Which function has the greatest y- intercept


`f(x) = - 9 \cos(x)`

`f(x) = 8 \sin(x)`

`f(x) = 7 \cos(x)`

`f(x) = - 6 \sin(x)`

Answer 1

the answer is
f(x) =-9 cos(x)

because cos and sin keep fluctuating between 1 and -1
as -9 x -1 is 9 so it is the greatest
