I've got to find the period, amplitude and graph a trig function similar to the one below and I'm not sure if I'm on the right track. I haven't posted the exact question so if something doesn't look right with the function that's why.
From that I think it's:
Period: 1 ie
Is raised up 8 on the y/sin axis so the max and minimum values are 11 and 5 with nothing to shift it right so graphing will pass through the point (0, 11)
Does that all seem right?
And what changes by there being a minus sign between the 8 and 3 rather than an addition?
Would the y axis start at the minimum point (5) rather than the maximum (11)?
