Question

Me ajudem pleaseeeeeweeeeeee

Answer 1

Resposta:

A) Im= {-13, -8, -3, 2, 7, 12, 17, 22}

Explicação passo-a-passo:

f(x)=5x+2

D= {-3, -2, -1, 0, 1, 2, 3, 4}

f(-3)=5(-3)+2= -15+2= -13

f(-2)=5(-2)+2= -10+2= -8

f(-1)=5(-1)+2= -5+2= -3

f(0)=5.0+2= 0+2= 2

f(1)=5.1+2= 5+2= 7

f(2)=5.2+2= 10+2= 12

f(3)=5.3+2= 15+2= 17

f(4)=5.4+2= 20+2= 22
