Question

Dada a função afimF(x) = 5 - 5x. Determina

A. F(0)
B. F(-1)
C. F(1\5)
D. F(-1\5)

Answer 1

Boa noite

f(x) = 5 -5x

a) f(0)
f(0) = 5 -5.0
f(0) = 5

b)f(-1)
f(-1) = 5 -5.(-1)
f(-1) = 5 +5
f(-1) = 10

c) f(1/5)
f(1/5) = 5 -5.1/5
f(1/5) = 5 -1
f(1/5) = 4

d)f(-1/5)
f(-1/5) = 5 -5.(-1/5)
f(-1/5) = 5 +1
f(-1/5) = 6

Bons estudos :)

Answer 2

a) f(0)= 5-5x
f(0)=5-5*0
f(0)= 5-0= 5
-----------------------
b) f(-1)= 5-5*(-1)
f(-1)= 5+5
f(-1)= 10
------------------
c) f(1/5)= 5-5*(1/5)
f(1/5) = 5-5/5
f(1/5)= 5-1= 4
---------------------
d) f(-1/5)= 5-5*(-1/5)
f(-1/5)= 5+5/5
f(-1/5)= 5+1= 6
