Question

Se h(x) = -1 + x, então, o valor de h(1) + h(1/2) + h(-1) é:

Answer 1

$h(x) = -1 + x \qquad\qquad h(1) + h( \frac{1}{2}) + h(-1)=? \\ \\ \\ h(1)=-1+1\to \boxed{h(1)= 0} \\ \\ h( \frac{1}{2}= -1+ \frac{1}{2}\to \boxed{ h\left( \frac{1}{2}\right) = - \frac{1}{2}} \\ \\ h(-1) = -1-1\to \boxed{h(-1)=-2} \\ \\ \\ h(1) + h( \frac{1}{2}) + h(-1)=0+(- \frac{1}{2})+(-2) \\ \\ h(1) + h( \frac{1}{2}) + h(-1)= - \frac{1}{2}-2 \\ \\ \boxed{ h(1) + h( \frac{1}{2}) + h(-1)= - \frac{5}{2}}$
