Question

Graph h (x) = 3 cos (2x) - 1 Use 3.14 for T. Use the sine tool to graph the function. The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.

Answer 1

Answer:

Step-by-step explanation:

We want to graph $h(x)=3\cos(2x)-1$.

We can graph this function easily by applying transformations to the parent function.

The base function is $f(x)=\cos x$

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
