The first one is constant. The second is quadradic and de second is is Absolute value.

Thank You, now what is part b) ????

anonymous · Answer

Tfhe third is a absolute value function. The answers are for the first is a ordered pair (3,2); For the second just plug the valeu f(3)=2(3)^2. For the absolute value plug the value in the expression and you will find out.

anonymous · Answer

you made a mistake for the first question its f(x)=x so what is it?

anonymous · Answer

and now whats part c) ????

anonymous · Answer

Sorry the first one is a line.

anonymous · Answer

Just plug the values in the equantions. For the first you have f(3)=3. So you will have the ordered pair (3,3).
