Question

b) F(x) = x²-2x+1 para x=-1,0,1,2,3

c) F(x) = x²-1 para x= -2, -1, 0,1,2

d) F(x)=-x²+1 para x=-2, -1,0,1,2

Answer 1

Vamos lá.

f(x) = x² - 2x + 1

f(-1) = 1 + 2 + 1 = 4

f(0) = 1

f(1) = 0

f(2) = 1

f(3) = 4

f(x) = x² - 1

f(-1) = 0

f(0) = -1

f(1) = 0

f(2) = 3

f(3) = 8

f(x) = -x² + 1

f(-1) = 0

f(0) = 1

f(1) = 0

f(2) = -3

f(3) = -8
