SAT 2 math help question ??? If f(x)= ax^2 + bx + c, how must a and b be related so that the graph of f(x-3) will be symmetric about the y-axis? A. a=b B. b=0, a is any real number C. b=3a D. b=6a E. a=1/9 b it would be great if you could explain....how many methods can you solve this ....show all of them ...thanks ...
