Elija la función exponencial que es decreciente

f(x)=(13)xf\left(x\right)=\left(\frac{1}{3}\right)^x

f(x)=(13)xf\left(x\right)=\left(-\frac{1}{3}\right)^x

f(x)=(13)xf\left(x\right)=\left(\frac{1}{3}\right)^{-x}

f(x)=3xf\left(x\right)=3^x

La definición de la función exponencial es:

f(x)=ax a>0 y a=1f\left(x\right)=a^x\rightarrow\ a>0\ y\ a=1

f(x)=ax a>0 y a1f\left(x\right)=a^x\ \rightarrow\ a>0\ y\ \ a\ne1

f(x)=ax a<0 y a1f\left(x\right)=a^x\ \rightarrow\ a<0\ y\ a\ne1
