12. The function Fis defined as following
X IF X > 2
F(x) = 2 IF-2< X 52
X+4 IF XS-2
Sketch the graph of F(x)
ii) Determine the domain and range of (F(X)
i)
13 (a) Find the inverse of R = {(x, y): y = 3x -2}
And hence determine its domain and range
(b)Draw the graph of R
If R = {(x, y): x + y 2 and x - y <4}

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the answer is stop cheating on things stoopid
