you have a graph, so all the questions get answered from your eyeballs, not from an equation or some kind of algebra
the period is the length over which the function makes one complete cycle. take a look and see where it is at its peak, and the next peak. the length of of that interval (on the x axis) is the period
the amplitude is half the distance from the lowest most point on the graph to the upper most point
thank you so much
yw if you would like me to check your answer let me know
amplitude is 4 correct?
yes from -5 to 3 is 8 units, half of that is 4
so for period its the highest arc to the lowest arc
how do i find midline?
it is half way between -5 and 3
as the name suggests it is the horizontal line that is "midway" between the max and the min
and no, the period is not from the highest to lowest
okay so the answer is A?
cause the midline is -1
yes, a rare A
thank you i appreciate it
