Question

Dada a função f(x) = 2x2 + 3x + 1, calcule:

a) f(- 1)

b) f(0)

d) f(- 2)

e) f(2)

c) f(1)

f) f(3)

Accepted Answer

a) f(-1) = 2(-1)² + 3(-1) + 1 = 2 + (-3) + 1 = 0
b) f(0) = 2(0)² + 3(0) + 1 = 1
c) f(1) = 2(1)² + 3(1) + 1 = 6
d) f(-2) = 2(-2)² + 3(-2) + 1 = 8 + (-6) + 1 = 3
e) f(2) = 2(2)² + 3(2) + 1 = 8 + 6 + 1 = 15
f) f(3) = 2(3)² + 3(3) + 1 = 18 + 9 + 1 = 28

Answer

f(-3)=
