Answer:
The amplitude of the given sinusoidal function is 3.5
Step-by-step explanation:
The given sinusoidal function is
[tex]m(x)=-3.5\cos x[/tex]
This function is of the form:
[tex]m(x)=a\cos bx[/tex]
where
a=|-3.5|=3.5 is the amplitude.
Therefore the amplitude of the given sinusoidal function is 3.5
