Question

si f(x) = x²+3x-4 calcula
f (-3)=
f(o)=
f(3) =​

Answer 1

Respuesta:

f(-3)= -4

f(0)= -4

f(3)= 14

Explicación paso a paso:

f(-3)=(-3)-3+3(-3)-4=0

f(0)=(0x0)+3(0)-4=-4

f3)=(3x3)+3(3)-4=14

Answer 2

Respuesta:

f(x) = x²+3x-4

F(x) =(x+4)(x-1)

F(-3)= (-3+4)(-3-1)

F(-3)=(1)(-4)

F(-3)= - 4

O diractamente

F(x) =x²+3x - 4

F(0)=(0)²+3(0) - 4

F(0)= - 4

F(x) = x²+3x - 4

F(3)= (3)²+3(3)-4

F(3)= 9+9 - 4

F(3)= 18-4

F(3)= 14
