True/ False \( \quad \) [5 Marks] Indicate whether the statement is true or false. 1. The \( y \)-intercept of the exponential function \( y=6^{x} \) is 1 . 2. If \( f^{-1}(x)=5^{x} \), then \( f(x)=\log 5 x \). 3. The graph of \( f(x)=\log (x+3)-4 \) is the graph of \( f(x)=\log x \) translated 3 units left and 4 units down. 4. Logarithmic functions are defined only for positive values of the base that are not equal to 1 . 5. All exponential functions have a vertical asymptote.
