document.write( "Question 341749: I need to find the vertex and axis of symmetry to graph the quadratic form, I understand how to graph quadratic forms but the fraction in this specific problem has me all jumbled up. I tried solving it and got x= 9/4 for the axis of symmetry and (9/4,87/16)for the vertex but im almost 100% certain that is wrong. I would really appreciate some help (PLEASE HELP ME). Thanks in advance.
