Question

Dada a função do 1° grau definida por f(x)=3x- 6, determine:

Answer 1

a) f(x) = 3x - 6

x = -2

f(-2) = 3(-2) - 6

f(-2) = -6 -6

f(-2) = -12

b) f(0) = 3(0) - 6

f(0) = 0 - 6

f(0) = -6

c) f(0,5) = 3 (0,5) - 6

f(0,5) = 1,5 - 6

f(0,5) = - 4,5

d) f(1) = 3(1) - 6

f(1) = 3 - 6

f(1) = - 3

e) f(2) = 3(2) - 6

f(2) = 6 - 6

f(2) = 0

f) f(12) = 3(12) - 6

f(12) = 36 - 6

f(12) = 30
