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.
1 answer:
Answer:
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

Answer: D, -1
First, plug in the value -1 for x in f(x) first.
can then be simplified to 
because 
. Next, put the value -1 for x in the equation g(x). This will look like 
.
The final step is to evaluate f(x) divided by g(x). f(x) = 1/2 and g(x) = -1/2, so when divided, you get -1.
