Question

As raizes e os vetices da funcao f(x) =3x²-4x 1? heeelllpppp :)

Answer 1

f(x) = 3x² - 4x + 1
f(1) = 3 . 1² - 4 . 1 + 1
f(1) = 3 - 4 + 1
f(1) = 0

f(2) = 3 . 2² - 4 . 2 + 1
f(2) = 3 . 4 - 8 + 1
f(2) = 5

f(0) = 1

f(√2) = 3 . √2² - 4 . √2 + 1
f(√2) = 3 . 2 - 4√2 + 1
f(√2) = 6 - 4√2 + 1
f(√2) = 7 - 4√2
