Question

Dada a função f(x)=3x²+1, calcule:
a)f(1) b)f(2) c)f(5) d)f(0)

Answer 1

Resposta / Explicação passo a passo:

Função:  f ( x ) = 3x² + 1

Calcule:

a) f ( 1 )

f ( x ) = 3x² + 1

f ( 1 ) = 3 ( 1 )² + 1

f ( 1 ) = 3 . 1 + 1

f ( 1 ) = 3  + 1

f ( 1 ) =  ........ 4 ( Resposta )

b) f ( 2 )

f ( x ) = 3x² + 1

f ( 2 ) = 3 ( 2 )² + 1

f ( 2 ) = 3 . 4 + 1

f ( 2 ) = 12  + 1

f ( 2 ) =  ........ 13 ( Resposta )

c) f ( 5 )

f ( x ) = 3x² + 1

f ( 5 ) = 3 ( 5 )² + 1

f ( 5 ) = 3 . 25 + 1

f ( 5 ) = 75  + 1

f ( 5 ) =  ........ 76 ( Resposta )

d) f ( 0 )

f ( x ) = 3x² + 1

f ( 0 ) = 3 ( 0 )² + 1

f ( 0 ) = 3 . 0 + 1

f ( 0 ) = 0  + 1

f ( 0 ) =  ........ 1 ( Resposta )
