Question

Dada+a+função+f:+IR_IR,definida+por+f(×)=+5×+2,+calcule+:+f(0),f(2),f(-3)+e+f(2/3) E urgente

Answer 1

Explicação passo-a-passo:

f(x) = 5x + 2

Temos que:

• f(0) = 5.0 + 2

f(0) = 0 + 2

f(0) = 2

• f(2) = 5.2 + 2

f(2) = 10 + 2

f(2) = 12

• f(-3) = 5.(-3) + 2

f(-3) = -15 + 2

f(-3) = -13

• f(2/3) = 5.2/3 + 2

f(2/3) = 10/3 + 2

f(2/3) = 10/3 + 6/3

f(2/3) = 16/3

Answer 2

Oie, Td Bom?!

f(x) = 5x + 2

f(0) = 5 . 0 + 2

f(0) = 0 + 2

f(0) = 2

f(2) = 5 . 2 + 2

f(2) = 10 + 2

f(2) = 12

f(- 3) = 5 . (- 3) + 2

f(- 3) = - 15 + 2

f(- 3) = - 13

f(2/3) = 5 . 2/3 + 2

f(2/3) = 10/3 + 2

f(2/3) = 10+6/3

f(2/3) = 16/3
