## madixy 3 years ago Determine the domain f(x) = 4/x^2

1. Libniz

what happen if you put 0 for x

it would equal 0

3. Libniz

no

oh 4

5. Libniz

no

Domain =R-{0}

because if u put zero in the denominator of a fraction that will give you a math error..

Whenever you are given a fraction and u need to find its domain ,take the denominator and equal it to zero then solve and the result will be the domain in the form R-{result} ...

So I have to find the range first?

i didn't say find the range ! Just equal it to zero x^2=0 x=0 Domain=R-{0}

what is R then? haha I'm sorry

oh result

oh oh ohhhh thank you. It just clicked! :) THANKS!

R=Real numbers

Thats mean the domain is all real numbers except Zero :)
