Question

1) Dada a função do 1° grau definida por f: R → RI f(x) = x2 – x-6, determine:
a) f(0)
b) f(1)
c) f(-2)
d) f(2)​

Answer 1

Resposta:

a) F(0) = 0.2 - 0 - 6

   f(0) = -6

b) f(1) = 1.2 - 1 - 6

   f(1) = 2 - 7

   f(1) = - 5

c) f(-2) = -2.2 - 2 - 6

   f(-2) = -4 - 8

   f(-2) = -12

d) f(2) = 2.2 - (+2) - 6

   f(2) = -4
