Question

1. Calcule F(3), F(5) e F(7) das funções do primeiro grau abaixo:
a) y = 6x + 2
b) y = – 30x - 6
c) y = – 2x - 34
d) y = 0x

Answer 1

Resposta:

Oie!

Explicação passo-a-passo:

Vamos lá!

a) y = 6x + 2

y = 6.3 + 2

y = 18 + 2

y = 20

y = 6.5 + 2

y = 30 + 2

y = 32

y = 6.7 + 2

y = 42 + 2

y = 44

b) y = – 30x - 6

y = – 30.3 - 6

y = – 90 - 6

y = – 96

y = – 30.5 - 6

y = – 150 - 6

y = – 156

y = – 30.7 - 6

y = – 210 - 6

y = – 216

c) y = – 2x - 34

y = – 2.3 - 34

y = – 6 - 34

y = – 40

y = – 2.5 - 34

y = – 10 - 34

y = – 44

y = – 2.7 - 34

y = – 14 - 34

y = – 48

d) y = 0x

y = 0.3

y = 0

y = 0.5

y = 0

y = 0.7

y = 0
