Here's the problem(s)
For #3 I need to find the cos graph equation here's what I got: shift to the right 2, Amplitude = 3, b = π/2 (pi/2)
equation: y=3cosπ/2(x-2)
I'm just not sure if i have it in the right format or if I'm even right
Attempt for #4 Amplitude=2 Shift left = 1 Shift up= 3
I'm just not sure if I am doing it right for both of them
#4 look right to me! ***Actually I take that back, I had to look at it again. Looks like your period is wrong. To find the period on this one, distribute your terms after you sin function:
Your period/end points of the new period should be -1, 7
**Remember that for the sin graph, your periods will not begin at the top and bottom of the curve, those will be for your cos graph. This is kind of silly, but I try to remember that a complete period of the cos graph has one big bump and a complete period of the sin graph has 2 bumps. LOL! Hope that helps!
