Question

Seja a função F(x)=x²-x-2 determine
a) F(1)
b) F(3)
c) F(0)

Answer 1

A) F(1)=1²-1-2    F(1)=-2
B) F(3)=3²-3-2   F(3)=9-3-2   F(3)=4
C) F(0)=0²-0-2    F(0)=-2

Answer 2

a)
f(x) = x² - x - 2
f(1) = 1² - 1 - 2
f(1) = 1 - 3
f(1) = - 2
-------------------------------
b)
f(3) = 3² - 3 - 2
f(3) = 9 - 5
f(3) = 4
-----------------------------------
c)
f(0) = 0² - 0 - 2
f(0) = - 2
