Which list correctly states the standard properties of $y=b^x$ for an admissible base $b$? Where $b>0$ and $b\ne 1$.

• A. $y$-intercept: $(0,0)$Horizontal asymptote: $y=1$Domain: $(-\infty ,\infty )$Range: $(-\infty ,\infty )$
• B. $y$-intercept: $(1,0)$Vertical asymptote: $x=0$Domain: $[0,\infty )$Range: $(-\infty ,\infty )$
• C. No interceptsNo asymptotesDomain: $(-\infty ,\infty )$Range: $(-\infty ,\infty )$
• D. $y$-intercept: $(0,1)$Horizontal asymptote: $y=0$Domain: $(-\infty ,\infty )$Range: $(0,\infty )$

Answer: (D)
