Which value of x will make this fraction undefined? 5/x-3

When x=(3). Assuming f(x)=5/(x-3) and y=f(x), then the fraction is undefined when x=3, as (3-3)= 0, so.. 5/0. This is due to the fact that any number divided by a Zero is undefined (  # / 0)  because  it means essentially-- Number/Zero = (An unkown number multiplied by the denominator to give that specified numerator in the equation. And there is no known number-- (#)*(0) --(In this case) that will give the number (5).

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
