f:\mathbb R\to\mathbb R

be defined by

f(x)=\dfrac{|x-2|}{x-2}

for

x\neq2

. a. (i) Simplify

f(x)

separately for

x>2

and for

x<2

. b. (ii) Name the parent function family represented by the simplified form and justify your answer using two distinct properties. c. (iii) Determine the domain and range of

f

and draw a rough sketch of its graph on the number line, indicating all key points. d. (iv) State, with reason, whether

f

is even, odd or neither.
