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

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

What is the rate of change of a line that passes through (2,-5) and (6,-2)?
