Question

Dada a função de primeiro grau f(x) = 2x + 3, qual é o valor de f(10) – f(-10)? ​

Answer 1

Boa Tarde !!!

$f(x) = 2x + 3\\\\\\Trocamos\ x\ por\ 10\ e\ depois\ por\ menos\ 10\\\\\\f(10)=2.10+3\\\\f(10)= 20 +3\\\\f(10)=23\\\\\\f(-10)=2.(-10)+3\\\\f(-10)=-20+3\\\\f(-10)=-17\\\\Espero\ ter\ ajudado\\\\Melhor\ Resposta\\\\Att:LDC$
