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:
Solution
7)
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
