Given m(x)=7/5x2+9-2 what is the domain of m in set notation form?

  • Calculus -

    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}
