Question

f(x)= 54x+45, determine o valor de f(2 541) - f(2 540)

Answer 1

f(x) = 54.x + 45
f(2541) = 54.2541 + 45 => f(2541) = 137259
f(2540) = 54.2540 + 45 => f(2541) = 137205

f(2541) - f(2540) = 137259 - 137205 = 54

Answer 2

Resposta:

54

Explicação passo-a-passo:

Função do 1° grau!

$f(x)=54x+45\\f(2541)=54\times2541+45\\f(2541)=137214+45\\f(2541)=137259$

$f(x)=54x+45\\f(2540)=54\times2540+45\\f(2540)=137160+45\\f(2540)=137205$

$f(2541)-f(2540)=\\137259-137205=\\\boxed{54}$
