Question

Sendo f(x) = 2x - 3 e g(x) = x - 4, calcule f(-3) + g(-2)

Answer 1

$\mathsf{f(x)=2x-3}\\\\ \mathsf{f(-3)=2\cdot(-3)-3}\\\\ \mathsf{f(-3)=-6-3}\\\\ \mathsf{f(-3)=-9}\\\\\\ \mathsf{g(x) = x - 4}\\\\ \mathsf{g(-2)=-2-4}\\\\ \mathsf{g(-2)=-6}\\\\\\ \mathsf{f(-3) + g(-2)=-9+(-6)}\\\\ \mathsf{f(-3) + g(-2)=-9-6}\\\\ \boxed{\mathsf{f(-3) + g(-2)=-15}}$
