Question

data a função f(x)=2×-1 calcule

a)F(-2)

B)F(¹/³)

C) F(¹/²)

D)F(6)​

Answer 1

Explicação passo-a-passo:

f(x) = 2x - 1

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

f(-2)= -4-1

f(-2) = -5

b) f(1/3)= 2.1/3 - 1

f(1/3) = 2/3 - 1

f(1/3)= 2 - 3

____

3

f(1/3)= - 1/3

c) f(1/2) = 2.(1/2) -1

f(1/2)= 2/2 - 1

f(1/2)= 1 - 1

f(1/2)= 0

d) f(6)= 2.6 - 1

f(6)= 12 - 1

f(6)= 11
