If we know the vertex of this parabola as the point (h,k), we can write the equation of the parabola as y=a(x−h)2+k for some unknown leading coefficient. Answer and Explanation: Since we know the vertex of this parabola, we can wr...
Use the quadratic formula to find any x intercepts on the graph of the equation Find the x-intercepts of the following quadratic functions. y = (x + 3)^2 + 9 y = -3x^2 + 13x - 4, use the quadratic formula to find any x intercepts on the graph of th...
The quadratic equation is the one that has as principal exponent a two; we can also call it a second-degree equation. We can solve this by factoring in or applying the quadratic formula. We must identify the values of the c...
