Question

What is the amplitude of the cosine function corresponding to the secant function graphed below ? a. -2 b. -1 c. 2 d. 3

Answer 1

Answer:

2

Step-by-step explanation:

From the graph, we obtain the trigonometric function as:

$y=2 \sec x+1$

The corresponding cosine function have equation.

$y=2\cos x+ 1$

This function is of the form: $y=a\cos bx+c$

where $|a|$ is the amplitude.

Therefore the amplitude is |2|=2

The third choice is correct
