Answer:

Step-by-step explanation:
The square of a complex number is a complex number. Here, we have:


We then have this system of equations:


Solving this system:










You would subitute -2 for x in the equation
f(-2)=x^2-6
PEMDAS so exonents
-2^2-6
negative times a negative= positive
4-6
f(-2)=-2
f(x) means that you subsitute x for x in the equation exg
f(1)=x+2 means f(1)=1+2
f(4)=x+2 means f(4)=4+2
Answer:
the solutions are c because, when we say x +7=81 that will give us 74 which is there on c
Answer:
Line segment CD and Line BC are not represented.
Step-by-step explanation:
Line segment CD is not represented because a line segment is a portion of a line that has 2 distinct end points.
Line BC is not represented because a line is a straight path that has no beginning nor an end
Ray BC is represented because a ray is a part of a line which has one end point and extends infinitely in one direction.
Point B is represented because we can see a dot at B indicating that B is a point.
