Answer: 17. Domain: x is all real numbers

Range: y>=0

18. r=2

Explanation:

17. f(x)=|x-2|

|x-2|>=0

x-2>=0

x>=2

x-2=<0

x=<2

x can be less than, equal to, or greater than 2. Hence,

Domain: x is all real numbers

|x-2|>=0 ==> f(x)>=0

Hence, the range is:

Range: y>=0

18. m=(y2-y1)/(x2-x1)

2=(9-3)/(5-r)

2=6/(5-r)

2(5-r)=6

5-r=3

r=2
