Question

Dada a função f(x) = x 2 − 5x + 6, calcule: a) Os zeros da função b) f(0) c) f(10) d) f(0) − f(10)

Answer 1

a) x² - 5x + 6 = 0

  (x - 3)(x - 2) = 0

  x = 3, 2

b) f(0) = 0² - 5.0 + 6

   f(0) = 6

c) f(10) = 10² - 5.10 + 6

   f(10) = 100 - 50 + 6

   f(10) = 56

d) f(0) - f(10) = 6 - 56 = -50
