Using the three trigonometric functions can be used to calculate unknown side lengths and angle in a right-angle triangle only.

But, if ever you we're given to find a non right-angle triangle, you will have to use sine rule or cosine rule.

Let the function f(x) have the form fx) = Acos(x+C). To produce a graph that matches the one shown below, what must the value of

slava [35]

Answer:

B. 4

Step-by-step explanation:

The given function is of the form:

$f(x) = A \cos(x+C).$

A is called the amplitude of the given function.

We can read from the graph that, the function ranges between:

-4 and 4

This implies that:

$|A| = 4$

Therefore the amplitude of the function is 4.

Hence the value of A must be 4.
