Explanation Given info: y = x 2 + 4 x + 6 Concept used: (1) To find the value of y-intercept put the value x = 0 (2) Find the minimum value by making squaring (3) Other point can be find out by putting suitable value of x in the expression Calculation: y - int e r c e p t y = x 2 + 4 x + 6 y ( 0 ) = ( 0 ) 2 + 4 ( 0 ) + 6 ( p u t t i n g x = 0 ) y ( 0 ) = 6 Hence y-intercept = 6 so point ( 0,6 ) Minimum value of y = x 2 + 4 x + 6 y = x 2 + 4 x + 6 = ( x ) 2 + 2 ( x )
