Question

Dado a função g(x)=x²+x+2 ,determine g quando x for:
x=1
x=2
x=3
x=0
x=-1
x=-2

Answer 1

Dado a função g(x)=x²+x+2 ,determine g quando x for:

x=1

g(1)= (1)² + 1 + 2

g(1) = + 1 + 3

d(1) = 4

x=2

g(2)= (2)² + 2 + 2

g(2) = 4 + 4

d(2) =  8

x=3

g(3)= (3)² + 3 + 2

g(3) = 9 + 5

g(3) =  14

x=0

g(0)=0² + 0 + 2

g(0) = 0 + 0 + 2

g(0) = 2

x=-1

g(-1)=(-1)² - 1 + 2

g(-1 ) = + 1 + 1

g(-1) = 2

x=-2

g(-2) = (-2)² - 2 + 2

g(-2) = + 4 + 0

g(-2) = 4
