Question

Dada a função definida por
f(x) = 2x-1 Calcule

a) f(0)


b) f(2)


c) f(-2)


d) f(5)

Answer 1

a) 2(0)-1= 0-1= -1
b) 2(2)-1= 4-1= 3
c) 2(-2)-1= -4-1= -5
d) 2(5)-1= 10-1= 9

Answer 2

A ) F(0) = 2.0-1 = 0 - 1 = -1

B ) F(2) = 2.2-1 = 4 - 1 = 3

C ) F(-2) = 2.(-2)-1 = -4 - 1 = -5

D ) F(5) = 2.5-1 = 10 - 1 = 9
