Question

graph at least one full cycle of the following trig function, lable the amplitude midline and maximum and the intervals f(x)=2sin(x-pi/2)-1

Answer 1

`\begin{gathered} f(x)=2\sin (x-(\pi)/(2))-1 \\ Maximum=1 \\ \text{midline}=(1+(-3))/(2)=(1-3)/(2)=(-2)/(2)=-1 \\ \text{midline}=-1 \\ The\text{ midline is y=-1} \\ \text{Interval = (0,2}\pi\text{)} \end{gathered}`
