Write the function as a set of ordered pairs. Give the domain and range of f.

Question

f(a)=t, f(b)=p, f(c)=r, f(d)=t

f=? (Type ordered pairs. Use a comma to separate answers as needed.)

Domain is ? (Type ordered pairs. Use a comma to separate answers as needed.)

The range is ? (Type ordered pairs. Use a comma to separate answers as needed.)

Answer 1

Given:     f(a) = t

              f(b) = p

              f(c) = r

              f(d) = t

As a set of ordered pairs (x, y), the function F is thus given by the following:

     F = {(a, t), (b, p), (c, r), (d, t)}

The domain (all possible x-values) of F is:

     Domain = {a, b, c, d}

The range (all possible y-values) of F is:

     Range = {t, p, r} 

Answer 2

f(1)=7,f(2)=-3,f(3)=5
