Direction:Which equation represents a quadratic equation?
Answer:Letter C. y=x(x²+1)
Why:The vertex of the quadratic y=x(x²+1)
They value of the vertex is found by substituting this into the formula for f (x).
Reason:Quadraticequations are actually used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object.
