Question

Dada a função:

f (x)= 2x - 5

Determine:

a) f ( 1 )=

b) f ( 0 )=

c) f ( -2 )=

Answer 1

f(1)=2.1-5= -3
f(0)=2.0-5=-5
f(-2)=2.(-2)-5=-9

Answer 2

Olá Carla!

Dada a função:

f (x)= 2x - 5

Determine:

a) f ( 1 )= 2 • 1 - 5

f ( 1) = 2 - 5

f( 1) = - 3

b) f ( 0 )= 2 • 0 - 5

f ( 0 ) = 0 - 5

f (0) = - 5

c) f ( -2 )= 2 • ( - 2) - 5

f ( - 2) = - 4 - 5

f (- 2) = - 9
