Given m(x)=7/5x2+92 what is the domain of m in set notation form?

I bet you meant ....
m(x) = (7/5)x^2 + 9x  2
= (7/5)[x^2 + (45/7)x ]  2
= (7/5)[x^2 + (45/7)x +2025/196  2025/196 ]  2
= (7/5)[(x + 45/14)^2  2025/196 ]  2
= (7/5)(x+45/14)^2  405/28  56/28
= (7/5)(x+45/14)^2  349/28 
I did not answer your question.
I read your other post first and assumed this one was the same type.
for this one the way you typed it,
the domain is
{x  x ∈ R}
