x(squared) -4x+4 = -11/3+4 becomes
(x-2)(squared) = 1/3
I understand I needed to factor to get the first part but I dont see how to get the 1/3...

hopefully you can understand, the computer doesnt really give me the option to write it correctly, thanks!

Please include the ordered pairs for each problem and the domain and range. I need a full solution.

1) {0,1,2,3...10} twice the abscissa more than one is equal to the ordinate

2) {1,3,5,7,9} the abscissa is one third the ordinate

3) {1,2,3,..9} the abscissa is a natural number and the ordinate is a prime number

could you please look at the example question on that page about it. i know you use cos(angle) = adjacent / hypotenuse
but do you have to use the angle between both sides in this case 60 or could you use any angle opposite in the far corner for instance if it was given to you?
