Question

Sendo f(x)=3× e g(x)=(1/4)×, dermine;

Answer 1

Resposta:

a) f(0) = 3 * 0 = 0

b) f(1) = 3 * 1 = 3

c) f(-4) = 3 * (-4) = -12

d) f( \frac{1}{3}) = 3 *  \frac{1}{3}  = 1

e) g(1) =  (\frac{1}{4})^{1} =  \frac{1}{4} 
  

f) g(2) =  ( \frac{1}{4})^{2} =  \frac{1^{2}}{4^{2}} =  \frac{1}{16}  

g) g(-3) = ( \frac{1}{4})^{-3} =  (\frac{4}{1})^{3} = 4^{3} = 64  

h) g( \frac{1}{2} ) =  (\frac{1}{4})^{ \frac{1}{2}} =  \sqrt{ \frac{1}{4}} =  \frac{1}{2}
