Given m(x)=7/5x2+9-2 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}
