The unit circle with center at the origin is a relation but not a function. a. Find the two functions which are semicircles of the unit circle, and determine their domains and ranges?
b. Are these functions onto functions? Justify.
c. Find the two functions which are lie in one Of the semicircle in part a, and determine their domains and ranges?
d. Are these functions one to one correspondence functions? Justify

i can answer this question sweetie!

step-by-step explanation:

step-by-step explanation: i dont

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
