Question

4. Dado f(x) = x2 + 7x + 10, calcule.
a) f(0)
b) f(1)
c) f(2)
d) f(-1)
e) (-3)
f) f(-5)​

Answer 1

Resposta:

b)f(1)

Explicação passo-a-passo:

2×+7×+10

9×+10

×=10-9

×=1

Answer 2

A) f(0) = 0×2+7×0+10×0 = 0

B) f(1) = 1×2+7×1+10×1 = 19

C) f(2) = 2×2+7×2+10×2 = 38

D) f(-1) = (-1)×2+7×(-1)+10×(-1) = -19

E) f(-3) = (-3)×2+7×(-3)+10×(-3) = -57

F) f(-5) = (-5)×2+7×(-5)+10×(-5) = -95
