Question

Dada a função exponencial f(x)= (-1)^x determine:
A. F(0)
B. F(2)
C. F(1)
D. F(3)

Answer 1

a) f(0)= (-1)^0
    f(0)= 1

b) f(2)= (-1)²
    f(2)= 1

c) f(1)= (-1)¹
    f(-1) = -1

d) f(3)= (-1)³
    f(3)= -1

Answer 2

a)
                 x
f(x) = (-1)
f(0) = (-1)º
f(0) = 1

*******************************
b)
f(2) = (-1)²
f(2) = 1

**********************
c)
f(1) = (-1)¹
f(1) = - 1

*********************
d)
f(3) = (-1)³
f(3) = - 1
