Answer:

4

Step-by-step explanation:

A função em questão, f(x), é:

[tex]f(x)=4x-9[/tex]

Primeiramente calcule os valores das funções para x=5 e x=6:

[tex]f(5)=4*5-9\\f(5)=11\\f(6)=4*6-9\\f(6)=15[/tex]

Em seguida, subtraia f(5) de f(6):

[tex]f(6)-f(5) = 15-11\\f(6)-f(5) = 4[/tex]

A resposta para o problema é 4
