Question

dada a função f(x)= 5x-4 calcule= f(0) f(-1) f(2) f(1/5)

Answer 1

f(x)=5x-4

f(0)=5.0-4
f(0)=-4

f(-1)= 5.(-1)-4
f(-1)= -5-4
f(-1) =-9

f(2)= 5.2-4
f(2)= 10-4
f(2)= 6

f(1/5)= 5.(1/5)-4
f(1/5)= 5/5-4
f(1/5)=1-4
f(1/5)= -3

Answer 2

Olá.

• f(x) = 5x - 4

a) f(0)

f(0) = 5.0 - 4
f(0) = -4

b) f(-1)

f(-1) = 5(-1) - 4
f(-1) = -5 - 4
f(-1) = -9

c) f(2)

f(2) = 5(2) - 4
f(2) = 10 - 4
f(2) = 6

d) f(1/5)

f(1/5) = 5(1/5) - 4
f(1/5) = 1 - 4
f(1/5) = -3

Bons estudos.
