Quadratic relations 2

Question

What is the formula needed to find the x-intercept, the coordinates of vertex and how would you put that equation in standard form in quadratic relations 

Answer 1

To find the x-intercepts of a quadratic, you would set the function to zero and solve for x.   You can graph, factor or use the quadratic equation 

 

The vertex formula for a quadratic equation is f(x) = a(x-h)² + k where (h, k) is the vertex.   To get this into standard form, you would need to foil out (x-h)² and simplify
