Question

10. A possible equation for the sinusoidal function shown below is YA MMMM TT 0 31 2 TE 2 TT 2 37 2 1 -2 a. y = -2 cos x + 1 b. y = 2 cos TX c. y = - COSTEX + 1 d. y = -2 cos x

Answer 1

10.2012 since, y = cosa and y= 2000 D 12 and y=-2001 14 2 - -2 which is so, as given graph not true. and y-26062+1 3 a T 1 which is also not game as given graph 6 option is also false. SI

Also, since y = Costu) Ty - 1 and y = 2688( 4 10 Here, which is also not same as given graph. to, option 5 is not true. and y = --Cos(4x) AY 1 le and y= - COS(T) + 1 2 . 74 which is fame as given graph. so option is true.

Thanku Any doubt please comment I'll help ou.
