Explicação passo-a-passo:
a)
f(-2) = 1. (-2) - 3 = - 2 - 3 = -5 (-2, -5)
f(-1) = 1. (-1) - 3 = - 1 - 3 = -4 (-1, -4)
f(0) = 1.0 - 3 = + 0 - 3 = -3 (0, -3)
f(1) = 1.1 - 3 = + 1 - 3 = -2 (1, -2)
f(2) = 1.2 - 3 = + 2 - 3 = -1 (2, -1)
b)
f(-2) = 2. (-2) + 5 = - 4 + 5 = 1 (-2, 1)
f(-1) = 2. (-1) + 5 = - 2 + 5 = 3 (-1, 3)
f(0) = 2.0 + 5 = + 0 + 5 = 5 (0, 5)
f(1) = 2.1 + 5 = + 2 + 5 = 7 (1, 7)
f(2) = 2.2 + 5 = + 4 + 5 = 9 (2, 9)
f(3) = 2.3 + 5 = + 6 + 5 = 11 (3, 11)
c)
f(-2) = - 5. (-2) + 0 = + 10 + 0 = 10 (-2, 10)
f(-1) = - 5. (-1) + 0 = + 5 + 0 = 5 (-1, 5)
f(0) = - 5.0 + 0 = + 0 + 0 = 0 (0, 0)
f(1) = - 5.1 + 0 = - 5 + 0 = -5 (1, -5)
f(2) = - 5.2 + 0 = - 10 + 0 = -10 (2, -10)
d)
f(-2) = 2. (-2) - 1 = - 4 - 1 = -5 (-2, -5)
f(-1) = 2. (-1) - 1 = - 2 - 1 = -3 (-1, -3)
f(0) = 2.0 - 1 = + 0 - 1 = -1 (0, -1)
f(1) = 2.1 - 1 = + 2 - 1 = 1 (1, 1)
f(2) = 2.2 - 1 = + 4 - 1 = 3 (2, 3)
e)
f(-2) = - 2. (-2) + 5 = + 4 + 5 = 9 (-2, 9)
f(-1) = - 2. (-1) + 5 = + 2 + 5 = 7 (-1, 7)
f(0) = - 2.0 + 5 = + 0 + 5 = 5 (0, 5)
f(1) = - 2.1 + 5 = - 2 + 5 = 3 (1, 3)
f(2) = - 2.2 + 5 = - 4 + 5 = 1 (2, 1)
