<p>I'm not very good at math. I'm average.
What is the domain of f(x) = 1/ radical 2x -4?
a) x< 2
b)x=2
c) x>2
d) x is greater than or eqaul to 2</p>
<p>The answer is C.</p>
<p>The denominator cant be equal to 0 or else its a math error so that eliminates B </p>
<p>An even radical cant have a negative value inside of it so x cant be less than 2.</p>
<p>That leaves us with x>2</p>
<p>I knew it. My teacher said thats wrong. He is stupid.</p>
<p>Well, it really depends on what exponent the radical is, but I’m assuming it’s to .5, so the answer would be C.</p>
