Which function has the smallest x-intercept value, if it exists? fx=3x-9 fx= 1/x +4 fx= square root of x+1 fx=x2

A Write properties of function: x intercept/zero: x = 3B Write properties of function: x intercept/zero: x = - \dfrac{1}{4}C Write properties of function: x intercept/zero: x = -1D Write properties of function: x intercept/zero: x = 0
