Question

seja a função f(x-4)=x³+1. O valor de f(0) + f(-5):

a)67
b)66
c)65
d)56
e)54

Answer 1

dados:
f(x-4)=X^3+1

f(0)+f(-5)=??

f(4-4)+f(-1-4)=??
___________________________________________________________
f(x-4)=X^3+1                 f(x-4)=X^3+1
f(4-4)=4^3+1                 f(-1-4)=-1^3+1
f(4-4)=65                       f(-1-4)=0
f(0)+f(-5)=65+0
letra "C"

obs:

f(4-4)=f(0)     f(-1-4)=F(-5)
