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.

See  attachment

Step-by-step explanation:

We want to graph .

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

The base function is

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

step-by-step explanati∵∵∴∴on:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
