Answer:The correct answer option is: 4.Step-by-step explanation:We are given the following two functions and we are to find the value of [tex] ( f - g ) ( 5 ) [/tex]:[tex]f(x) = x^2 - 5[/tex][tex]g(x) = 4x - 4[/tex]Finding [tex] ( f - g ) ( x ) [/tex]:[tex] ( f - g ) ( x ) [/tex] [tex]= (x^2-5)-(4x-4) = x^2-4x-5+4[/tex][tex]( f - g ) ( x ) = x^2-4x-1[/tex]So, [tex]( f - g ) ( 5 ) = (5)^2-4(5)-1 = 4[/tex]
