Question

Dada a função f(x)=2x elevado a 2 -3x-2 , obtenha f(-2) , f(-1) ,f(0) ,f(2) e f(3)

Answer 1

Dada a função f(x)=2x elevado a 2 -3x-2 , obtenha


f(-2) =>2.(-2)^2-3.(-2)-2=>2.(4)+6-2=>8+4=>12

f(-1) =>2.(-1)^2-3.(-1)-2=>2+3-2=>3

f(0) =>2.(0)^2-3.(0)-2=>0-0-2=>-2

f(2) =>2.(2)^2-3.(2)-2=>2.(4)-6-2=>8-8=>0

f(3)=>2.(3)^2-3.(3)-2=>18-9-2=>18-11=>7


espero ter ajudado!

boa tarde!
