Math Question: Find the x-intercept of the reciprocal function f(x) = 1/x. Answer: The x-intercept is the value of x where f(x) equals zero. For f(x) = 1/x, setting f(x) = 0 leads to 1/x = 0. However, this equation has no solution since we cannot divide by zero. Therefore, the reciprocal function has no x-intercept.
