Question

{ (-4, -7), (-1,-4), (6,8), (6,-8) }

a. domain= {6,-4,-1,-6}; range ={8,-7,-4,-8}

b. domain ={8,-7,-4,-8}; range ={6,-4,-1}

c. domain={6,-4,-1,16}; range= {8,-7,-4,-8}

d. domain= {6,-4,-1} ; range= {8,-7,-4,-8} my answer

Answer 1

You're right.

Answer 2

I agree with your answer (d).

As a function, normally,



               y = f(x)

Thus, the y-value in  an (x,y) coordinate is the range, and the x-value the domain.
