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}

What is the answer to |-2x-5|-|-4+8| and x=7

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?
