Question

Como resolvo isso?

Sendo f(x) = 5x - 3, determine:

(a) f(0) =

(b) f(-3) =

(c) f(6/5) =

Answer 1

f(x)=5x-3

a)
f(0)=5(0)-3
f(0)=-3

b)

f(-3)=5(-3)-3
f(-3)=-15-3
f(-3)=-18

c)
f(6/5)=5(6/5)-3
f(6/5)=6-3
f(6/5)=3

Answer 2

Sendo f(x) = 5x - 3, determine:

(a) f(0) = 5.(0) - 3=0-3==> - 3

(b) f(-3) = 5.(-3) - 3= - 15 -3==> - 18

(c) f(6/5) = 5.(6/5) - 3= 6 -3==>  3
