How do you graph and list the amplitude, period, phase shift for y=tan(theta-pi/2)-2y=tan(θπ2)2?

See below.

Explanation:

Amplitude:

The tangent function has no definable amplitude. This is because:

as theta->pi/2color(white)(8888)tantheta->ooθπ28888tanθ which is undefined.

Period:

period of tantheta=pitanθ=π

period of tan(theta-pi/2)-2=pitan(θπ2)2=π ( No change in period )

Phases shift:

Subtracting pi/2π2 from thetaθ causes a shift in the positive/right direction by pi/2π2
