Answer:
In the given function if the value of a increases then:
Step-by-step explanation:
The amplitude of a sine or cosine function is the maximum distance it could go above or down the mid-line of the function.
The cosine function f(x) is given by:
[tex]f(x)=a\cos x[/tex]
where |a| denote the amplitude of the function.
( The amplitude of the function:
[tex]f(x)=\cos x[/tex] is 1 )
Also, the period of this function is: 2π
Hence, if a increases then the amplitude of the function will increase.
