1. find the zeros of
I got 0,-7,3 was hoping someone could do it and see if they get the same answer.
I got no real zeros
3. Find the amplitude, period and phase shift.
I got: amplitude = 1, period = pi, phase shift = pi/2
Any help on any of them is EXTREMELY welcome. Thanks a million
*edit* just put this in the pre calc help area seeing as I think I will get replys quicker and then noticed in the rules not to double post and I dont want to be a pest there a delete button for the entire thread?
For number one I didnt think there were any real zeros of the left hand side of the equation or at least not any that i could find. Graphing it I noticed that the parabola did cross the x axis but i tried using those numbers and it did not come out to exact zeros.
