Step-by-step explanation:
We want to graph [tex]h(x)=3\cos(2x)-1[/tex].
We can graph this function easily by applying transformations to the parent function.
The base function is [tex]f(x)=\cos x[/tex]
The transformed function has an amplitude of 3 but is shifted 1 unit down, so the minimum value is -4 and the maximum is 2.
The function is shrunk horizontally by a factor of 1/2.
The graph of the transformed function is shown in the attachment
