Question

Dada a função f(x) = 2x -3, determine:

a) f(1) = ______

b) f(-1) = ______

c) f(0) = ______

d) f( 1/2) = ______​

Answer 1

Resposta:

a)

f(1) = 2.1-3 = 2 -3 = -1

f(1) = -1

b)

f(-1)=2.(-1) -3 = -2-3= - 5

f(-1)= -5

c)

f(0)= 2.0-3= -3

f(0) = -3

d)

f(1/2) = 2.1/2 -3 = 1-3 = -2

f(1/2) = -2
