Question

Dada a função f(x)= x + 3 , calcule:

a) f(0):

b) f(1):

c)f (-5):

Answer 1

f(x) = x + 3 

f(0) = 0 + 3 = 3 

f(1) = 1 + 3 = 4 

f(-5)  = -5 +3  = -2 

Answer 2

f(x) = x + 3

x = 0

f(0) = 0 + 3 = 3

x = 1

f(1) = 1 + 3 = 4

x = - 5

f(-5) = - 5 + 3 = - 2

Resp.:
a) f(0) = 3
b) f(1) = 4
f(-5) = - 2
