Explanation Given information: Given parabola y = 1 10 x 2 − 3 x + 50 . Formula used: If the given parabola is of the form y = a ( x − h ) 2 + k , then the vertex of the parabola is ( h , k ) . Calculation: The given parabola can be rewritten as, y = 1 10 x 2 − 3 x + 50 ⇒ y = 1 10 ( x 2 − 30 x ) + 50 ⇒ y = 1 10 ( x 2 − 2 ( 15 ) x ) + 50 ⇒ y = 1 10 ( x 2 − 2 ( 15 ) x + ( 15 ) 2 − ( 15 ) 2 ) + 50 ( adding and subtracting ( 15 ) 2 ) ⇒ y = 1 10 ( ( x − 15 ) 2 − ( 15 ) 2 ) + 50 ( since ( x 2 − 2 a x + a 2 ) = ( x − a ) 2 ) Now, ⇒ y = 1 10 ( ( x −</

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.
