If f ( x ) = - 3 x 2 and g ( x ) = 2 x , evaluate the composite function ( g o f )( x ). => - 6 x or - 6 x 2 + x or - 6 x 3 or - 6 x 2..

If two functions are defined by f ( x ) = x 2 - 3 and g ( x ) = 1 x - 9 , then write the domain of the composite function ( f o g )( x ). => R - {9} or (-1, ∞) or (0, ∞) or R..

If f ( x ) = 5 x - 9 and g ( x ) = 5 x 3 , find the value of the composite function ( g o f )(3 x ). => x 3 - 15 or (15 x - 27) 3 or 15( x 3 - 5) or 5(15 x - 9) 3..

Evaluate the composite function ( f o g )( x ). Given f ( x ) = 3 x + 4 and g ( x ) = x - 6. => 3 x - 24 or 3 x - 2 or 3 x 2 - 14 x - 24 or 3 x - 14..

Find the mode of the set of letters. F, C, H, F, G, K, G, K, N, K => K or Q or C, K or C..

Bodies allowed to fall freely were found to fall at the same rate irrespective of their masses (air resistance being negligible). The velocity of a freely falling body increased at a steady rate i.e., the body had acceleration. This acceleration is called acceleration due to gravity - 'g'..
