Question

Função do 2 grau por favor me ajude !!

Answer 1

Y = 3*X² - 2*X

a) f(2) = 3*(2)² - 2*(2) = 12 - 4 = 8
a) f(2) = 8

b) f(-3) = 3*(-3)² - 2*(-3) = 27 + 6 = 33
b) f(2) = 33

c) f(0) = 3*(0)² - 2*(0) = 0 - 0 = 0
c) f(0) = 0

d) f(1/3) = 3*(1/3)² - 2*(1/3) = (1/3) - (2/3) = -1/3
d) f(1/3) = -1/3
