It is effective after students have graphed parabolas in vertex form ($y = a(x h)^2+k$), but have not yet explored graphing other forms. The $y$-intercept is $(0, -3)$, which is visible as the constant in $y_2$ since the other terms are 0 when you plug in $x = 0$. Most or all students in Algebra 2 have seen, analyzed and graphed quadratic functions. Now change the equation of your graph to: EMBED Equation.3 7. There is simply no way to make an analogous equation for any polynomial of degree y for y>4, not enough operations are defined by the rules of mathematics. If asked for the exact answer (as usually happens) and the square roots cant be easily simplified, keep the square roots in the answer, e.g. For the quadratic formula, I have a quick question.
