Part I – Vertex Form of a Quadratic Equation For each parabola, state the coordinates of the vertex and the direction which it opens 1) y = 2(x – 5)2 + 3 2) y = -(x + 17)2 – 12.5 3) y = x2 – 5 Put each equation in vertex form. Then state the coordinates of the ...
Fireworks – Vertex Form of a Quadratic Equation • Vertex form y = a·(x – h)2 + k allows us to find vertex of the parabola without graphing or creating a x-y table. y = (x – 2)2 + 5 a = 1 vertex at (2, 5) y = 4(x – 6)2 – 3 a = 4 vertex at (6, –3...
What is the equation of the quadratic function whose vertex of the graph is on the xx-axis and passes through the two points (1,4)(1,4) and (2,8)(2,8)? Here is my attempt: Use the vertex form of a parabola f(x)=a(x–h)2+kf(x)=a(x–h)2+k where...
