Question

Let the function f(x) have the form f(x) = Acos(x + C). To produce a graph that matches the one attached inside, what must the value of A be?

(graph will be inside!)

A. 4

B. 3

C. 2

D. 1

**not sure :( please explain? :)

Answer 1

graph :)

Answer 2

Would you agree that A is the amplitude?

Answer 3

yes :)

Answer 4

What is the amplitude of the graph?

Answer 5

umm is it 3?

Answer 6

yes. Since the graph goes up to 3 and down to -3, the amplitude is 3

Answer 7

So choose B

Answer 8

okay... ohh i seee, so it was just asking what the amplitude was??

Answer 9

Yes. It asked us to find A and A is the amplitude.

Answer 10

awesome! thank you :)
