Explanation Formula used: The standard form of the equation of the parabola with its axis along the x -axis and vertex at the origin is y 2 = 4 p x , where, ( p , 0 ) is focus of the parabola and x = − p is directrix of the parabola. Calculation: Consider the given focus of the parabola, ( 3 , 0 ) . The vertex of the parabola is ( 0 , 0 ) . By the formula given above, p = 3 and the directrix of the parabola is x = − 3 . In order to find the equation of the parabola substitute the value of p into the formula given above as follows

Maximization

Have you ever seen a bridge in the shape of a parabola? Where is its maximum on the bridge? The maximum of that bridge is the highest point on that bridge. The process of finding the maximum of the bridge here is called the maximization.
