i missed this blog. OOPS! i totally forgot. i guess i was looking forward too much to the holiday. but ill make up the missed blog now.
i think i understand all there is that goes along with the graphing we learned last week
if i just make sure i remember and follow the steps one by one carefully it really isnt a hard concept to grasp.
i do have a little blip of confusion when it comes to distinguishing wether there is a horizontal shift or a vertical shift.
i think i just need an explanation of what to look for to decipher which shift is necessary
any help though would be wonderful!
thanks

With graphing cosine and sine functions everything depends on the equation.
ReplyDeletey=Asin(Bx-h)+C
The h in the equation signifies the horizontal shift, and be sure to do the opposite.
ex. y=2sin(3+2)-4
For your horizontal shift, you would move he points 2 units to the left.
The C in the equation signifies the vertical shift, and for this shift you DO NOT do the opposite.
Ex. 3sin(2-3)+1
For the vertical shift, you would move your points 1 unit upward.
