For graph to the right Amplitude Midline y Period Equation

For graph to the right: Amplitude: Midline: y = Period: Equation using sine: Equation using cosine:

a)amplitude =(6-(-2))/2=4

b)midline y =(6-2)/2=2

y=2

c)period =11-1=10

2/B=10 =>B=/5

vertical shift =2-0=2

horizontal shift =-C/B=1

=>C=-B=-/5

d)y =(4sin((/5)x -(/5))) +2

e)y =(4cos((/5)x -(/5)-(/2))) +2

y =(4cos((/5)x -(7/10))) +2
