An HVAC technician is monitoring pressure changes in a system that follow a basic logarithmic scale represented by the function $f(x) = \ln(x)$. When reviewing the graph of this pressure model, where should the technician expect to see the curve cross the vertical $y$-axis?

A health and safety officer is graphing the intensity of sound exposure using the basic logarithmic function $f(x) = \log_{10}(x)$. True or False: This graph will intersect the vertical $y$-axis, representing a noise level at an intensity of zero.

A laboratory technician is graphing the concentration of a chemical solution using the basic logarithmic function $f(x) = \log_{10}(x)$. Since the domain of this function is restricted to strictly positive values ($x > 0$), the graph will have ____ $y$-intercept(s).
