Question

Si: f(x) = x2 + x + 1; hallar: f(3)
Si: M(x;y)=(x+y)2 - (x - y)2 Calcular: M(25;11)

Answer 1

Respuesta:

f(3) = 10

M(25;11)=44

Explicación paso a paso:

f(x) = x2 + x + 1

f(3) = x2 + x + 1

f(3) = 3(2) + 3 + 1

f(3) = 10

M(x;y)=(x+y)2 - (x - y)2

M(25;11)=(25+11)2 - (25 - 11)2

M(25;11)=72 - 28

M(25;11)=44
