b) ]7,10]
c) ]- ∞,2]
d) ]-5, 0[
e) [-12,-6[
f) ] -2, + ∞ [
g) [1,7[

Answer 1

Explicação passo-a-passo:

$a)~~[-3,1] \mapsto---\bullet^{-3}xxxxxxxxxx\bullet}1----\\ \\\\ b)~~]7,10] \mapsto----\circ^7xxxxxxx\bullet^{10}----\\ \\ \\ c)~~]-\infty,2] \mapsto xxxxxxxx\bullet^2------$

$d)~~]-5,0[ \mapsto -----\circ^{-5}xxxxxxxxxx\circ^0----\\ \\ \\ e)~~[-12,-6[~\mapsto ----\bullet^{-12}xxxxxxxxx\circ^{-6}-----\\ \\ \\ f)~~[-2,+\infty[~\mapsto-----\circ^{-2}xxxxxxxxxxxxxxxx\\ \\ \\ g)~~[1,7[~~\mapsto ~---\bullet^1xxxxxxxxxxx\circ^7--------$
