    Well, yeah. Just change the f(x) to y. It kind of makes it easier when you look at it. Now, how do you plan to solve it?

    Yes, but to do so, you're going to have to apply the Quadratic Formula Does that sound familiar or am I getting way ahead of you?

    \[\frac{ 3\pm i \sqrt{23} }{ 4 }\] This was my answer btw...

    Then again I used the quadratic formula. You could find a different answer by completing the square. I don;t know where you are in your lessons... Does Completing the Square sound familiar?
