Answer
It doesn't make sense
Work Step by Step
We are given the rational function:
$$f(x)=\dfrac{x-3}{x-7}.$$
The function is defined for all real $x$ except the zero(s) of the denominator.
Determine the zero(s) of the denominator:
$$x-7=0\Rightarrow x=7.$$
So we must exclude the value $7$ from the domain.
The given statement does not make sense.
