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}
