Question

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

Answer 1

this is the graph

Answer 2

@hartnn @.Sam.

Answer 3

have you seen A cos x graph?

Answer 4

keep in mind that

Acos( Bx + C ) + D

C = horizontal shift, C > 0, to the left, C < 0, to the right

Answer 5

A. 2
B. 3
C. 4
D. 1

Answer 6

And I'm trying to find that graph..

Answer 7

can you tell me how much the graph of Acos x has shifted ? and on which side ? right or left

Answer 8

thats a rough sketch, but will do for this problem
