Question

dada a função F (x) =2× + 1 determine
a ) f (-1)
b) f (0)
c) f (3) ​

Answer 1

Oie, Td Bom?!

• Seja a função f(x) = 2x + 1.

a) f(- 1) = 2 . (- 1) + 1 = - 2 + 1 = - 1

b) f(0) = 2 . 0 + 1 = 0 + 1 = 1

c) f(3) = 2 . 3 + 1 = 6 + 1 = 7

Answer 2

Resposta:

A) -1=2x+1

2x=+1+1

2/2=1

b) 0=2x+1

2x=0+1

1/2 = 0,5

C) 3=2x+1

2x= -3+1

2x= -2

-2/2= -1
