You can put this solution on YOUR website!
Domain specifies the possible values of 'x' for your equation:
f(x)= 1/x^2 + 9

The only values that will make the equation undefined is when the denominator of 1/x^2 equals zero:
This is true only when x does NOT equal 0
Therefore the range is "all real numbers except 0"
