Answer:
Step-by-step explanation:
Domain means the inputs, usually that's what we call the x , as in the equation having the "x"
so what can't we put into x?
well the one thing we can't put into x if if we get a zero in the denominator. so 7* [tex]\frac{5}{7}[/tex] would make 5 and the 5-5 would be zero.. so we can't include 5/7 in the domain
so everything but 5/7 is the domain
