Question

Dada a função f(x)=x2+10x+25Calcule:1-f(-8). 2-F(-2). 3-F(-5)

Answer 1

Calculando...

f(-8) = (-8)² + 10*(-8) +25
f(-8)= 64 - 80 + 25
f(-8) = 64-55
f(-8) = 9

f(-2) = (-2)² + 10*(-2)+25
f(-2) = 4 - 20+25
f(-2) = 4+5
f(-2) = 9

f(-5) = (-5)²+10*(-5)+25
f(-5) = 25 -50 +25
f(-5) = 0


======

1 - 9 . 2 - 9 . 3 - 0
1 - 18 - 27
1 - 45 = -44
