Question

alguém me ajuda a resolver essas funções?? tentei mas errei todas!

Answer 1

a) f(1) = 3.1² - 1 + 4
f(1) = 3 - 1 + 4
f(1) = 6

b)f(-1) = 3.(-1)² - (-1) + 4
f(-1) = 3.1 + 1 + 4
f(-1) = 8

c)f(0) = 3.0² - 0 + 4
f(0) = 4

d)f(1/2) = 3.(1/2)² - (1/2) + 4
f(1/2) = 3(1/4) -1/2 + 4
f(1/2) = 3/4 - 1/2 + 4
f(1/2) = (3 - 2 + 16)/4
f(1/2) = 17/4
