Question

05. Dada a função f(x) = 2x-3, determine:
a) f(1) =
b) f(-1) =
c) f(0) =
d) F(1/2) =​

Answer 1

a)

f(1) = 2 . 1 - 3

f(1) = 2 - 3

f(1) = - 1

b)

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

f(- 1) = - 2 - 3

f(- 1) = - 5

c)

f(0) = 2 . 0 - 3

f(0) = 0 - 3

f(0) = - 3

d)

f(1/2) = 2 . 1/2 - 3

f(1/2) = 1 - 3

f(1/2) = - 2

Resposta:

a) - 1

b) - 5

c) - 3

d) - 2
