Question

me ajudem pleasee!!!!​

Answer 1

Resposta:

Explicação passo a passo:

a. f(x)=x³

x=-2

f(-2)= (-2)³=-8

x=-1

f(-1)=(-1)³=-1

x=0

f(0)=0³=0

x=1

f(1)=1³=1

IM={-8,-1,0,1}

b. f(x)=-x+3

x=-2

f(-2)=2+3=5

x=-1

f(-1)=1+3=4

x=0

f(0)=0+3=3

x=1

f(1)=-1+3=2

Im={2,3,4,5}

c. f(x)=1-x²

x=-2

f(-2)=1-(-2)²=1-4=-3

x=-1

f(-1)=1-(-1)²=1-1=0

x=0

f(0)=1-0²=1-0=1

x=1

f(1)=1-(1)²=1-1=0

Im={-3,0,1}
