Please help me. I am in dire need of assistance. I don't know how to change fractions such as 1/7 in a quadratic function. The problem is like this: y= (-7x^2)+2x The directions are as follows: Complete these steps for a function. a)Tell whether the graph of a function opens up or down. b)Find the coordinates of the vertex. c)Write an equation of the axis of symmetry. For my equation of the axis of symmetry, I got: -2/2(7)=-2/-14=-1/-7=1/7 Please explain the next step. Do I round the decimal? Do I leave 1/7 as a fraction? HELP!!!!!!!!!!!!!
