Answer:
Step-by-step explanation:
f( x ) = 5x^2 - 4x - 5
f( 1 ) = 5 ( 1 )^2 - 4 ( 1 ) - 5 = 5 ( 1 ) - 4 - 5 = 5 - 9 = -4
f( -1 ) = 5 ( -1 )^2 - 4 ( -1 ) - 5 = 5 ( 1 ) + 4 - 5 = 5 + 4 - 5 = 9 - 5 = 4
f( 0 ) = 5 ( 0 )^2 - 4 ( 0 ) - 5 = 5 ( 0 ) + 0 - 5 = 0 + 0 - 5 = 0 - 5 = -5
f( 1 ) + f( -1 ) - f( 0 ) = ( -4 ) + 4 - ( -5 ) = -4 + 4 + 5 = 5
