Calculate the constant of proportionality
x 2 4 6
y 7 14 21

which  best  describes the transformation from the graph of  f(x) =  x2  to the graph of  f(x) = (x  – 3)2  – 1?   left 3 units, down 1 unitleft 3 units, up 1 unitright 3 units, down 1 unit  right 3 units, up 1 unit

Can any one me with the answers to these questions asap?
