Question

Dada a função f(x)=2^x pede se:
a) f(3)
b) f(-1)
c) f(-4)
d) f(-1/2)
e) f(5)

Answer 1

Bom dia, Julia!

$a) f(3) = 2^{3} = 2.2.2 = 8. b) f(-1) = 2^{-1} = \frac{1}{2} = 0,5. c) f(-4) = 2^{-4} = \frac{1}{2}.\frac{1}{2}.\frac{1}{2}.\frac{1}{2} = \frac{1}{16}. d) f(-1/2) = 2^{-\frac{1}{2}} = \sqrt{2^{-1}} = \sqrt{\frac{1}{2}}. e) f(5) = 2^{5} = 2.2.2.2.2 = 32.$

Espero ter ajudado!
