f(x)=9x+4 and listed in interval notation
also:
f(x) x2+14x+40
in interval notation
and:
1/x^2+81 (interval notation)
and:
x+11/x^2121 (interval notation)
and:
f(x+2)
f(x)=6x^2x+7
You have listed a lot of functions but have said nothing about what the interval is. Unless you specify an interval for the variable x, there is no specific intervl for f(x). For further discussion, see http://mathforum.org/library/drmath/view/52929.html
