Question

dada las funciones y(x)= 2x2-5x+3 y g(x)=1 -4x-x2 calcula f (-2)+ g(2) =

Answer 1

Respuesta:

F (x)= 2x²-5x+3

f(-2)= 2(-2)² -5(-2)+3

f(-2)= 2(4) +10+3

f(-2)= 8+13

f(-2)= 21

g(x)=1 -4x-x²

g (2)= 1 -4(2) -(2)²

g(-2)= 1 -8- 4

g(-2)= -11

calcula

f (-2)+ g(2)

21 +(-11) =

21 -11 = 10
