Question

hello i really need some help!

How does changing the function from f(x) = −4 cos 3x to g(x) = −4 cos 3x − 6 affect the range of the function?

The function shifts down 4 units, so the range changes from −4 to 4 in f(x) to −8 to 0 in g(x).

The function shifts down 4 units, so the range changes from −1 to 1 in f(x) to −5 to −3 in g(x).

The function shifts down 6 units, so the range changes from −4 to 4 in f(x) to −10 to −2 in g(x).

The function shifts down 6 units, so the range changes from −1 to 1 in f(x) to −7 to −5 in g(x).

Answer 1

When you say \(\Large\color{black}{ \bf f(x)=Cx-d }\) that function is d units down from

\(\Large\color{black}{ \bf f(x)=Cx }\)

Answer 2

dont get it?
