1. Verify that the point is on the unit circle. Yes or No? If the point his not on the unit circle, explain why.
2. If the point is on the unit circle, find the sin, cos, and tan of the given point.
sin
COS
tan

x coordinate is none

step-by-step explanation:

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:
