Question

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

Answer 1

Explicação passo-a-passo:

f(x)= x² +7x + 10

f(0)= 0² +7.0 +10 = 0 +0 +10= 10

f(1)= 1² +7.1 +10= 1 + 7 +10= 18

f(2)= 2²+7.2 +10= 4 +14 +10= +28

f(-1)= (-1)² + 7.(-1) +10= +1 - 7 +10= -6+10= +4

f(-3)= (-3)² + 7.(-3) +10= +9 - 21 +10= +19 - 21= - 2
