Question

Preciso muito pra hoje

Answer 1

a)

D(f) = {0,1,2}

CD(f) = {-1,0,1,2}

Im(f) = {-1,0,1}

b)

D(g) = {-1,0,1,2}

CD(g) = {0,1,2}

Im(g) = {1,2}

c)

D(h) = {-1,0,1}

CD(h) = { -2,-1,0,1,2}

Im(h) = {-2}

d)

D(k) = {-2,0,1,2}

CD(k) = { -2,0,1,2}

Im(k) = {-2,-1,0,1,2}

Espero ter ajudado! ☄️
