Question

Dada a função definida por f(x)=x² -5x+6, determine f(0), f(2) e f(3). O resultado obtido respectivamnete é:

Answer 1

f(0)=$0^{2}$-5x(0)+6 = 6
f(2)=$2^{2}$-5x(2)+6 = 0
f(3)=$3^{2}$-5x(3)+6 = 0

Answer 2

f(x) = x² - 5x+ 6, determine f(0), f(2) e f(3)
f(0) = 0² - 5 · 0 + 6 = 0 - 0 + 6 = 6    ⇒ f(0) = 6
f(2) = 2² - 5 · 2 + 6 = 4 - 10 + 6 = 0  ⇒ f(2) = 0
f(3) = 3² - 5 · 3 + 6 = 9 - 15 + 6 = 0  ⇒ f(3) = 0
