Answer 1

Explicação passo-a-passo:

1) f(x)= 5x +1

a)f(1)= 5.1+1= 5+1=6

b)f(2)= 5.2+1= 10+1=11

c)f(3)= 5.3+1= 15+1= 16

d)f(0)= 5.0+1= 0+1= 1

2) f(x)= x - 2

a) f(-1)= (-1) -2= -3

b) f(0)= 0 - 2= -2

c)f(1)= 1 -2= - 1

d) f(2)= 2-2=0

3)

a) D(f)= { -3,-2,-1}

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

Im (f)={ 1, 2}

4)

b) D(f)= { -2,-1,0, 1,2,3}

CD (f)= { 1,2,3,4,5,6,7}

Im(f)= { 1,2,3,5,6}
