The discriminant D of a quadratic equation is the part of the quadratic formula under the square root −D=B2−4ACIt helps us determine the nature of the solutions −If D>0, there are two real and distinct solutions. If D=0, there is one real and repeated solution (a double root...
we can also see that it intersects the x-axis at two points,i.e. $x=\pm2$. This is another way of finding out roots. If the parabola just touches the x-axis at one point, the roots are the same and in that case, we can check D=0. Again if the parabola does not intersect ...
Just knowing those two points we can come up with an equation. Firstly, we know h and k (at the vertex): (h, k) = (1, 1) So let's put that into this form of the equation: f(x) = a(x-h)2 + k f(x) = a(x−1)2 + 1 Then we calculate "a": We know the point...
