If f(x) = 4 β x2 and g(x) = 6x, which expression is equivalent to (9 - 1)(3)?
Accepted Solution
A:
Answer:(g β f) ( 3 ) = 23Step-by-step explanation:( g β f ) ( x ) = g ( x ) β f ( x ) = 6 x β ( 4 β x 2 ) = x 2 + 6 x β 4to evaluate ( g - f ) ( 3 ) substitute x = 3 into ( g β f ) ( x )( g β f ) = ( 3 ) 2 + ( 6 x 3 ) - 4 =23
