Question

08) Dada as funções exponenciais abaixo, calcule e
faça o gráfico. X = (-2,-1, 0, 1, 2, 3)
d) F(x) 2*
e) F(x) (1/3)*
f) F(x) 4*

Answer 1

Resposta:

Explicação passo-a-passo:

X = (-2,-1, 0, 1, 2, 3)

d) F(x) 2*

f(x) = 2^x

f(-2)= 2^(-2)= (1/2)^2 = 1/4

f(-1)= 2^(-1) = 1/2

f(0)= 2^0= 1

f(1)= 2^1= 2

f(2)= 2^2= 4

F(3)= 2^3= 8

X = (-2,-1, 0, 1, 2, 3)

e) F(x) (1/3)*

f(x)= (1/3)^x

f(-2)= (1/3)^(-2) = 3^2= 9

f(-1)= (1/3)^(-1)= 3

f(0) = (1/3)^0= 1

f(1)= (1/3)^1 = 1/3

f(2)= (1/3)^2= 1/9

f(3)= (1/3)^3 = 1/27

X = (-2,-1, 0, 1, 2, 3)

f) F(x) 4*

f(x) = 4^x

f(-2) = 4^(-2)= (1/4)^2= 1/16

f(-1)= 4^(-1) = 1/4

f(0)= 4^0 = 1

f(1)= 4^1 = 4

f(2)= 4^2= 16

f(3)= 4^3 = 64
