Range of [tex]f:[/tex]  f = [-9,infin)f=[−9,∞) (iii)

Hence, Range of f = [-9,infin)f=[−9,∞) (iii) Representation of ff as a set of ordered pair = { (x,x^2-9) : x in R}{(x,x2−9):x∈R}

Sure hope this helps you

Note the rule

If f is given in ordered pair

  • For example if f is given in form of (x,y) pairs .

Then

  • Domain is x
  • Range is y

Hence our range is set of y values
